Please don't take this the wrong way, but you should read some anarchist political theory if you want to address their actual beliefs.
This is exactly the kind of communal structure that anarchists advocate for: a voluntary collective where everyone agrees to contribute to furthering certain goals, values, and objectives.
OP is not coercing players to be in their game or to do things their way; they're saying "this is the game that I run, take it or leave it," and the players can join if they share the same goals.
I could tell by your first comment that you didn't care to know about how others think.
Ignorance is a lot easier than educating yourself, so I can see why you'd choose the easy path; I'm just disappointed that you decided to be incurious instead of learning something.
But I'm sure your "highschool rebel" understanding of anarchism is truly accurate, thanks for the notes. Or you could explain what mental gymnastics I'm performing? This is all basic anarchist theory that you can confirm with a five minute read of a wikipedia article summary.
