The state you live in today, is the monopoly that resulted from a failure to establish anarcho-capitalism. As I've said many times, the confusion we have over what is meant by government is very destructive here. By "government" many ancaps simply mean "the state", which I absolutely agree is flawed thinking.
Now some of them would strive for more power, and that would be dangerous since that could start some kind of turf war or power intermingling, so it has to be made sure that things are well decentralized
This is pretty much how I see it. "Decentralized" might have to be discussed at lenght at some point, but in general this is how most anarcho-capitalists see society being constructed
I have already wrote a few articles about it, so I have a general feeling how it would look like, but I still haven't figured out every detail. I guess that is how evolution is done, people figure it out on the way.
I wish ancaps would view it this way, but I think you are just conflating your own view with theirs. Most of the ancap community that I have seen is pro-corporatist , pro IP enforcement and in some way even pro State. They are mostly Libertarians who just want low taxes, but they haven't exactly figured out the nature of the State yet.
Depending on how new you are to the community, you may have seen a big change as of these last few years. It's not anarcho capitalism that's changed, well not for the worse anyway. It's a mix of people changing, but also both cultural and political fascists outright trying to infiltrate the movement. I've said before that it's getting very ugly currently. People pick sides over both satirical and more serious memes etc. The fascist trolls love it.
There have been a few breakout attempts here and there to restart somewhere fresh, but it's impossible to keep the real ancaps separated from the non-ancaps unless it's a closed off space with serious vetting.
I originally come from the far left many years ago and have a lot of experience with the ideological divides. But consistent anarcho-capitalists are not actually "right wing" - as obviously the left, but also ancaps often claim when an entirely different spectrum is used for meassure - and would have to be voluntaryists.
It's always hard to be convincing in a comment section on the internet. Although I've discussed this a lot over the years, I see the reward diminish all the time. Hell the monarchists often outnumber the anarcho-capitalists in communities such as on Reddit and Facebook. So I'm not going to use the ancap label unless absolutely necessary from now on. All it does is prevent me from speaking with other center-libertarians that disown the concept.
