Anarchy is a political structure where there’s basically no one in charge, right? But wouldn’t that just create a power vacuum that would filled by organized crime, corporations, etc.? Then, after that power vacuum is filled, we’re right back at square one, and someone is in charge.
Are there any political theorists that have come up with a solution to this problem?


The UN is not a society. There are many groups without a leader. But when talking about anarchism, people usually mean anarchist society.
That’s like saying FAANG is anarchism, because they talk among themselves without there being a leader.
