To have a group you MUST make rules about - who's in or out, where is in or out, what happens when someone violates the rules of the group etc. If you have a group it's not anarchy.
1) not everything with a governance structure is a government (e.g. company) 2) governments have a monopoly on violence & citizens are forced to be part of it, without that not a gov.
What happens if they refuse to sign the contract? What happens if the child of a contract signer violates the contract? What if an internal group organizes to change the contract?
real question is why someone who wants to try this out needs your permission & you to be ok with every what-if scenario. Why can’t you let people do what they want?
Sounds like you don't have an answer 😂😂😂 I'm just trying to get to the bottom of the ideology by asking questions, you don't need my(or anyone's) permission lol
