It has nothing to do with "right or wrong". It has to do with the prerogative of the majority coin holders. It's very true that stake can be centralized much further than hashpower. All someone has to do to get more influence is purchase more stake. I'm not sure about the argument of "Chinese Miners" competing... Is there any business in China that isn't controlled by the govt? Is there anyone in China who has money that the govt doesn't want to have money?
I don't think it is really that simple. Obviously when the Chinese government imprisons or disappears someone or confiscates his or her assets, the previous day that person had money (and/or their freedom/life). The next day they don't.
Moreover the "Chinese Government" is not a unitary entity either.
Regarding the fact of minority stakeholders being taken advantage of by larger shareholders, I can only imagine a situation where the larger holders would destroy smaller holders currency. This of course would destroy the currency and its value and would not be in their interest to do so.
I gave you an example straight from Bitcoin. Setting transaction fees. That obviously accrues to the advantage of some parties an disadvantage of others. It probably doesn't crash the world and destroy the currency value, but it means if you can't protect your interests in the game, your best choice is to leave the game. Thus the ownership contracts until you have private equity that isn't at risk of being disadvantaged by anyone.
It won't work as money, which by its nature becomes universal. It might works as some sort of narrow platform that delivers utility to customers, or possibly a cooperative that delivers utility to its owners, but the ownership will be narrow. That is inevitable.
(And I'd add that since I have serious doubts are there being a useful application for blockchains other than money, it may not work for anything, but that's another question really.)
