Apologies, I seemed to have missed your point.
So what are you implying with "it's still critical for gaining control of the network" before?
Just that centralization or any kind of attack would still rely upon gaining a large majority of hashrate on the network. Lots of people were irked by the idea of PoS Bitcoin
Now there's an alternative: adjust to zero-conf PoW, or adopt PoS rejuvenated/perfected with Avalanche.
The issue with PoS was when it is coupled with Nakamoto consensus, isn't it?
