Yeah Agorism is how I would choose to define it.
How do you define anarchy in this conversation? It’s a word that’s been co-opted and the meaning distorted. Similarly to socialism and communism, just according to their original definitions.
Rothbard and others refer to themselves as anarchists or anarcho-capitalists and have written extensively about these types of economic philosophies. Opt in, market / economic driven societies. I thought this is what you were referring to. Maybe we’re just not defining the word in question the same to start.
