Do you mind giving a few examples? I can't think of any communities like that.

I think they main incentive that drives people to initially become moderators is the desire to keep the community they operate in clean and rule abiding.

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.
