But the problem is the growing banning of PoW mining due to what others think that don't share your belief.
Proof of Work is harder to ban than other consensus like Proof of Stake. In PoS you cannot reliably prove if someone is DDoSed or is only pretending to get advantage by slashing. In PoW if there is a monopolist, it has to keep working to hold that position, in PoS the validator can sign every competing chain and always be rewarded. In PoW when someone has 51% computing power, then turning off some miners may even be profitable, so it is natural pressure against centralization (imagine you have 100% computing power, then there is no reason to mine blocks starting with 80 zero bits and pay high electricity bills, you can save money by letting the difficulty drop). In PoS when someone has 51% coin supply, then there is no reason to give up. Once 51%, always 51%, it is true in PoS, because you can sign every chain using different addresses and pretending that you are not a monopolist and you can still control everything without making any additional effort, like in PoW where you have to keep your mining equipment running.
You can tell you only know what PoW supporters have told you.
Everything you think you know is literally wrong.
I suggest actually study of a PoS coin so you can learn why you are wrong.
I tell you, but you seem to have trouble believing me, so research it your self.

Hint :
PoS staking % is not a constant. (
51% attacks are easier on PoW networks.)

That is all the help , I am giving you, do the rest of the research on your own.
That argument says nothing. The PoS architecture itself limits the number of pool operators that can be there for optimal netowrk efficiency. Anything beyond that is just useless as those pools neither get significant reward nor ever participate as they'll never get the leader slots.
For example, you quote ADA. This currently has around 2500 pools. The optimal value as per their spec is 500. This means the system isn't really efficient already. Then there is the fact that exchanges are operating multiple nodes to increase their own stakes. Decentralization and censorship-resistance are two factors that come to mind.
When a PoS network actually becomes valuable and is at scale, the amount of manipulation that the central players can do to centralize the network and profit from the reward in those cycles is insane. EOS is a prime example.
Thus, you maybe trying to show that you have done your research, it is pretty incomplete. I frankly don't think this deserves a spot in Technical Discussion and
I had started a thread for people who wanted to prove that Po(Insert your favorite word) is better alternative to PoW. Maybe you should bring the arguments.
