Yep, I’m not denying many of todays government functions are useless, but complete anarchy is almost impossible to sustain. In an anarchic state all it takes is one bad actor/group to commit a crime before people decide they need some form of organized protection. A group of protectors forms and needs to be paid by the people they are protecting one way or another. For the group of protectors to work efficiently they need a leader/leadership group. Now you have an armed group with a leader. Who will the leader be? Will he be self appointed? Will he be elected? How do you keep the leader from abusing this position? What are the crimes this group should protect against? Who will decide whether someone is guilty? Shouldn’t there be a process for the people to decide the answer to all those questions? Shouldn’t the people be able to decide who runs the courts and what the laws are? Eventually legal system forms, courts form, an election process forms, rule making forms. Now you’ve already left anarchy and have entered the “night-watchman state” AKA minarchy. One bad person enters this minarchal system, abuses it and it expands - “what if I can convince these people to give me a little more money and in exchange I’ll build some roads for them, I’ll pick up their trash, etc?” People will buy in. The rest is history.
