If this is your quick comment then I fret to see the slow one 😊
To the topic. Self-voting is the easiest way to earn rewards. Major powerholders are doing it from day one onwards.
You do like your posts and comments, don't you? So why won't you vote them up? It's only natural to do so.
Yes, self-voting can be disabled with a few lines of code. But there are many ways around this ban.
Personaly, I don't see a problem here. It is a question of my steem and voting power. Both are earned and consumed by me as I see fit.
