Come on… who should limit who and by what standards? It is already self-regulating!

How is it self-regulating? The current growing concentration of wealth is a very documented and aknowledged thing, seen as a risk for global stability. Do you call that self-regulation?

Coming back to this question, I had a personal breakthrough thinking of limits, thank you! My main point being that no limit to power makes anarchism impossible, in that case power being essentially capital, how would you limit the concentration of power-capital without governements/states? If you could design the main asset of such a society to be anti concentration, you might have something that holds. If the main asset is money, and you distribute its creation for ever, then no one can cease it all (or an overwhelming part of it) and you get a balance of power by design. Cryptocurrencies give a great advantage to defence via personal holding of private keys. Bitcoin does that. This advantage is reinforced by privacy. As for distribution/creation, it should be infinite but with strictly limited inflation. Monero does that, but the more advanced work I have seen on this topic is "the relative theory of money", only in french here:

Sommaire — Théorie Relative de la Monnaie v2.718

All of this makes me actually think that under certain conditions, anarcho-capitalism could be a thing... Great talk haha!
