That would be in an immediately started anarchy. If the change occured gradually, over generations, with an increase in social responsibility among the people, they could function without a government. This does not mean there wouldn’t be any laws; anarchy means ‘without archons,’ literally, not without laws. It’s inherently based upon the principle that laws and taboos are well and good, but leaders are the ones who are flawed. Law enforcement, and how it would function, is a widely debated issue, if it is to exist at all.
In Spain, the most successful and idealistic anarchy to have existed so far, there were some types of police, but they were very loosely organized, and barely existed at all.
Anarchy’s most persistant and un-manageable problem is the issue of a military. Without any sort of leaders, and army does not function exactly well, at least it has not in the past. The lack of an organized, effecientdefensive body is what, in the end, caused the Spanish anarchy to fall, as well as many other would be anarchist states to fall in the past. The punching to blood on the sidewalk isn’t as prevelent as people assume and fear it will be, for the most part. Due to most people’s morals, if they’re going to murder or rape someone, the law would or will not get in their way; Japan has a notoriously apathetic/incompetant police force when it comes to dealing with issues like murder, but they still have less murders per year than America, with a much more active police force and government, does by far. The law, generally, won’t stop someone from doing something they already intend to do. Therefore, prevention will not be an issue, the only issue would be punishment, which brings us back to the question of to what degree an organized police force is to exist, if at all.
The corporation thing did not occur in Spain, but it’s one of the few issues where the difference in time periods really makes an impact; this is one of the more serious problems along with anarchy as well. However, as I said, there can be laws to limit corporations, as laws are allowed to function within an anarchy, so long as there aren’t leaders.
Now, while my idealogy runs with anarchy, this is all a very long way off in some idealogic future, with careful building up to it. I’d certainly never try and start an anarchist revolution to overthrow any government now, most places really aren’t ready for it, and would descend fully into chaos. So, for right now, I’m pretty much going to be voting libertarian. But, it’s a nice idea of a direction to build the future into.
