I can't speak for @transisto but I would flag you and your self-upvotes if I didn't feel your content added value. I don't care if it is one vote per year. If it isn't deserved on the basis of the content adding value or evidencing of added value then the vote is undeserved. There is not such thing as 'wasted' vote power, because the vote power does not (and associated rewards do not) 'belong' to you, it is (they are) a community resource.
The sort of entitlement that you demonstrate in this comment (and also by putting it here in an offtopic thread just to bitch) makes me more likely to downvote you not less. But I won't do it unless I happen to see undeserved rewards (and I don't spend much time looking right now).
Whether a self-upvote is added value or not is or can be, theoretically at least, too subjective as opposed to being objective enough as value can be determined by subjective opinions based on non-shared principles, values, ideas. I say it is or can be more subjective and more 50 shades of grey, of gray, much more than we may know.
Everything about Steem content is subjective. None of the voting on Steem is objective in any real way. Even automated bot votes are done because the bot owner/developer subjectively believes that is a 'good' way to vote. This is all both by design and unavoidable. People downvoting in a manner that they, subjectively, feel is best is how things are supposed to work.
I'm actually not, personally, someone who is terribly hung up about self-voting. But when others do feel that way, that is their valid opinion, and it is perfectly okay that they act on it.
Be clear on this though: There is nothing objective going on here, ever. All upvotes and downvotes are subjective.

Agreed. I don't really care if people upvote themselves.
