Any revolution requires struggle, sacrifice, and difficulty, though. All the important social movements that have preceded the current sociopolitical climate were initially met with harsh criticism, aggressive opposition, and extreme doubt, but today we can all mostly agree that they were necessary and those hard times were well worth it. The movement that freed black slaves and eventually lead to equal rights for all races; the movement that lead to women being able to vote and work beside us; the fight for legal, safe abortions for women; the battles for unionists and workers’ rights; the overthrowing of dictatorships and oppressive regimes like the Nazis; the ongoing fight for more environmentally sustainable means of energy. Some things are still in the works today, but nothing worth fighting for comes easily.
Anarchism and/or socialism are just the most obvious next phase, as far as I’m concerned, especially as it becomes more and more clear how fed up even the most common of people are becoming, how out of control our institutions are getting, and how impossible it’s starting to get just to survive in these systems. So, yes, of course any kind of transitional phase will be incredibly difficult, but nothing as overbearing or traumatic as another century in this fucked-up system we’ve allowed to take over our world, our land, our fellow brothers and sisters, and our lives.
You’re wrong about one thing, though: We would not necessarily need everyone to be on the proverbial “same page”. That’s actually one of the reasons anarchism is so much better and accommodating than representative democracy. You see, in an anarchist society, people would coexist peacefully and communally, but would branch out into different structures based on their own personal concerns, preferences, and desires. The only real conjoining factor would be that leadership, hierarchy, and government would no longer exist to mediate this.
Anarchism would work based on a system of group decision-making known as consensus. Rather than holding semi-annual voting ceremonies where only the voices of the majority are heard or considered or represented, as in a democracy, communities would make mutual decisions together while resolving disagreements and coming to agreements on things that concern their community. Unlike in a democracy, where those who are not the majority are left to merely endure a world they must live in but whose conditions they had no say in, people who are unable to agree or find peace in a community have the option of finding a community where they will. The branching off of different cultures, ideologies, and styles of living would happen naturally as time went by and hostility like we see today would be greatly reduced to being nearly non-existent by the fact that people would finally have options to choose from. People would live autonomously and communities would only be as strong as the consensual peace and solidarity in their community is.
Technically speaking, laws are what create crimes. A lot of the harsh realities of our current system and society that you mention are mere symptoms of the system itself. A lot of these symptoms would become obsolete in an anarchist society, though. For example: No one would have the motivation or need to steal from anyone because everyone would have access to all that they wanted and needed, equally and without any kind of monetary or physical exchange; with the absence of capital, competition, currency, and property, the crime of theft would no longer exist. Considering how often conquest, theft, and desperate means of survival come into play as motivators for murder, imagine how rare violence would become in our world; no one would shoot people in convenience stores anymore, no one would fly buildings into planes anymore, no more wars over resources and capital gain would occur, violent drug cartels would disappear, drive-by shootings in turf wars wouldn’t go down anymore, cops wouldn’t be killing people to protect property, et cetera, et cetera.
As for other violent aberrant behaviors, such as senseless murders, child molestation, rape, and stuff of that sort, they would no longer be viewed as mere crimes that can be stopped with imprisonment or death, they would be viewed exactly for what they are: aberrant behavior. Biologically and evolutionarily speaking, violence as we know it today is not part of our species’ makeup, despite what many people believe and want you to believe. This behavior is not, as they say, “human nature”. If you look at the backgrounds of those who perpetrate acts of violence, rape, and murder, you will find that most, if not all, of them have some sort of history of abuse, neglect, and psychological problems themselves. It takes mental illness or conquest over property to cause these uglier aspects of mankind; it’s not something that runs in our blood. So when dealing with people who will act out in violent ways, we would treat them as ill, not as subhuman monsters. This sort of method is used in Norway and they have one of the lowest murder rates in the world. Meanwhile, countries such as America with high prison populations and heavy use of the death penalty have some of the highest instances of violent crime in the world. Fact is, prisons, the death penalty, and laws have never been effective deterrents or preventions of violent crime (or any crime for that matter).
Lastly, I wanted to explain how all of us people, all with different ideas and desires and attitudes, would live together peacefully despite differences. This would be a free society, not some cult where everyone would have to assimilate to the same exact ideals. You see, without capitalism turning us against one another in a constant competitive cycle over money and resources, without government controlling what we can and cannot do while violently forcing our life-long subservience, and without the institutions that operate within it segregating all human beings with useless abstractions like race, gender, orientation, religion, class, border, nationality, et cetera, we would only have each other to rely on. In a communal society, as I said earlier, our respective cells would only be as strong as our solidarity with one another and peaceful coexistence within them. To act out against the community, to try and enforce authority over others, to do something that interferes with the freedoms of another, to live in a way that harms the environment or your fellow man; these things would be not just harmful to the individuals involved, but to our society as a whole. Therefore, we would all be joined together in solidarity at all times with a new, more focused and sensible goal: to live together peacefully while maintaining a respectable and non-destructive relationship with our world. The consciousness would eventually be shifted by necessity; if we as individuals failed, our society would fail.
We would always have the alternative to this utopian society in the backs of our minds. I mean, look at where we are today with capitalism and democracy: environmental devastation, wars, drugs, government corruption, institutionalized bigotry, sweatshops, rape, corporate colleges, record-breaking unemployment, animal slaughter, religiously motivated terrorism, people stabbing homeless people, war veterans homeless on the street, bees disappearing… the list goes on.
