In well-policed communities where moderators actively listen to users, or where people feel reporting and flagging mechanisms work, I would imagine people generally feel empowered enough that they are satisfied remaining a regular user.

I don't think many moderators seek to expand their rulesets, as it really just becomes additional (often free) work for them. Increasing and enforcing more rules is a cost that is only worth bearing when what isn't being actioned is causing enough damage to warrant the additional work.
