What happens if there is no self upvoting at all? Posts included.

No clue. It hasn't been tried as far as I know. Though that is very easy to get around. Just delegate power to another account and up vote yourself with that.

So I don't think that is a solution either.

Yeah, I know.
There is plenty of that already I'd say. I just don't think a flag war is productive. It would be nicer if the 'don't be a dick' rule would self govern.

The second rule of Steemit should be "Don't be a dick." Covers basically everything rule #1 doesn't.

Yep. I agree.
