> What guarantees that this continues to be true? Yes coins that can't be sold are worthless, but coins that can only be sold with KYC aren't.
This applies to PoW coins too. Miners can't be anonymous if they want to sell their coins. Why would anybody mine for nothing?
> The staking providers or delegatees are the (potential) oligopolies
Yes, and miners mine in pools. Why are you not considering pools as (potential) oligopolies? What is the difference?
> Those are also anonymous and, if not completely portable, fungible with general electronic manufacturing equipment that's widely possessed.
They need physical locations with people physically present with physical inputs and outputs. The idea that it is easier for miners and hardware manufacturers to be anonymous than a guy spinning some software on some server is... stupid. To think that it is easier for miners and hardware producers to change location than a guy moving private keys from one server to another is just... retarded.
> Which supports my point - the capability to exclude a nation state also allows the staking cabals to exclude people they don't like.
I've asked you already how would a staking cabal exclude people they don't like and for some reason you are not answering that question. I'm guessing you are avoiding it because your answer, as all you've written so far in this thread, also applies to mining cabals.
> Given that a staking cabal by its very nature controls the chain, they can stop other people getting or making coins. But a mining cabal can't stop other people getting or making mining equipment.
No they can't make them stop making mining equipment, why do you think that that is relevant? The mining cabal can produce their own hardware and prevent anybody using any different hardware from joining the network, could they not?
Can you please try to clearly answer the original question. What makes mining oligopolies better than staking oligopolies? If you are sticking with your answer that it is harder to create mining oligopolies then please explain how? And before you press reply could you please stop for a minute and thing how what you wrote is applicable to mining oligopolies and not to staking oligopolies or vice versa.
