The only issue with this mindset is posting restrictions (e.g. on reddit) if your overall karma score drops too low.

Karma systems work great if everyone used them as intended, for quality of content or thought, but they're more often used for how much you agree with the sentiment of a comment and if it agrees with the philosophy of the person voting, regardless of the merit of the comment.

For that reason, I'm sure there must be a better way to do karma for a site that is made to be productive, and not just an echo chamber.
