There probably enough people with 1000+ karma to reduce potential groupthink. You just need three people to say "this comment doesn't inspire rage", not necessarily as far as "I really like this comment". That's still the upvote's role.
0-3 upvote hiding would massively inflate karma, as you'd have a minimum of 3 karma for every "acceptable" comment. Not to say it couldn't work, as the karma source is then at least slightly filtered, but it would change the fact you can post a ton of average but not inappropriate comments and maintain close to zero karma.
