Start a nice subreddit put all your time and energy into building a community then kicked out when you get old and watch it get handed over to someone else.

You're proposing a broken solution to the wrong problem.
What you should be asking is what can Reddit do to stop a handful of moderators from consolidating power?
And that's simple, don't let any account (or one person) be moderator of more than x subreddits. They won't though, they have millions and don't give a sh*t.
Actually i had in mind national, local and generic-name subreddits that are not really fungible because of reddit's horrible lack of decent search function. most of them grew because reddit was additing people there automatically.
Or generic words like 'cars' 'travel' or politics
