> As I've said repeatedly, it's different because staking means that the same people control both the current coin supply and the means of creating new ones. This is the first time you are saying that, and you aren't explaining how that is relevant to PoS oligopolies. What was said by me and by rtkwe, on this matter, is that due to this characteristic of PoS coins the only way, we can think of (you've ignored both of…
> a staking oligopoly can remain oligopoly is by controlling the majority of coins and not selling those coins which in effect means that a PoS oligopolies don't make any money from being oligopolies. In fact maintaining a staking oligopoly would destroy all the money that was invested in creating it. Eh, maybe. I think there's a lot of middle ground between selling freely/anonymously to anyone and not selling at all…
This also applies to staking oligopolies. Either all the coins are owned by the oligopoly rendering them valueless or they need to ignore blocks from others. Again, it seems that staking oligopolies are "better" than mining ones.
> Whereas if every time an outsider tries to buy some coins, their name didn't quite match for KYC and they need to resubmit their documents, or someone else bought them first, or the exchange suddenly needs to freeze all transactions to investigate an issue, you can maintain the illusion of an active market for quite some time.
This assumes that the exchanges are the oligopoly and ignores that the coins that the vast majority of coins that exchanges stake are owned by someone else and can be pulled. And no, if you freeze all transactions for whatever reason you can't maintain the illusion of an active market for quite some time.
