Lack of imagination.
Mods can still dump 10k trash messages in a sub making it unusable. (Or smart messages in the case of most subreddit who are trash anyway).
Set-up automoderator with rules reventing anyone below 5 billions karma to participate.
Ban everyone.
I’m sure there are a lot of other options.

Banning everyone takes a bot, which is rate limited. Same with a trash flood.
Automod though, you can easily set to do things like remove all new comments and submissions, remove stuff on one report (which lets you use the argument no one really believes that you’re letting the users have more control.), allow new submissions but lock every comment section, or allow only select users to post, whether based on karma, username, flair, etc.
Possibilities are endless really.
They’d get banned for spam.
