I think it will happen organically as we form communities (whatever form that they take).

Fiat rules won't be respected.

Laws will be agreed upon that are aligned with Bitcoin laws. I think fundamental to that is the ability to opt in & out of this new system. It has to be a choice, it doesn't mean there won't be a cost though.

I think the fewer laws, the better.

You would need to be rules on how to interact with the fiat world.

I think you'd probably need to establish some sort of way to settle disputes (some sort of court).
