System punish those who don't vote so they must vote somehow.

I can't agree with your assumption that stakeholders could be forced to upvote themselves just because there were no other options! Greed is a much simpler explanation. If you look for example at this account which (since HF 19 took place) posts about ten minimalistic 'articles' every day and upvotes them all with (now fourfold stronger) 100 %, then you cannot tell me he is forced to upvote himself, because nowhere on the Steemit platform could be found any other articles which are worth to be upvtoed:

There are enough good articles, and if everybody starts upvoting himself that will lead to big and unnecessary problems, frustration of the newbies and a decrease ot the Steem price.
I am a (even if not really big) stake holder of more than 50000 Steem as well and so far I believed in the success of the platform, but in case this problem continues to be ignored I may abstain from investing further money into Steem in future.

I already wrote an article about why self-voting has become a much bigger problem since HF 19 in my opinion.
