ol anarcho-capitalist is not anarchist?
No, I don't think it is. Anarcho-capitalism is rather about making power and governance dependent on money (in very very short), not about doing away with power and governance completely. (Which perhaps makes it somewhat more realistic, but that's another story)
This whole platform is built by two anarcho-capitalists. :D
So what? Is it anarchist? Does it do away with power and governance? No, it does not, owners decide rules, change them at their will and so on. (I'm not saying it's bad BTW)
