PoW has nothing to do with blocksize.
Dude you really don't understand the math of propagation. That is an idiotic claim.
Without verification of transactions in the prior block, PoW can't be safely devoted to mining the next block.
Scaling of block size is all about the fact that all miners have to verify all transactions. Which intimately tied to PoW.
If miners start trusting other miners by reputation instead of verifying, then you no longer need PoW. You can based the consensus proof-of-maximum-trust, i.e. trust is centralization.
then miners like antpool must be stupid, seeing how they signaling for a straight block size increase without knowing this or maybe what you are saying it's not 100% correct or partially missing something
no one still have correctly explained without flaming and be pretentious, why simply increase the block size MB do not scale, unless "scale" doesn't simply mean having more transaction per second
