I think we are at the polarization point in this debate where people are making "arguments" that they barely even believe themselves -- on both sides.  And no one is actually responding to the other side's concerns.  For example, I have not read any response to the problem that if bitcoin becomes a settlement currency it will centralize because the only people who will care to run full nodes will be companies who do settlement.

At this point further discussion is useless.

This argument even exists because either direction on the block side decision is flawed, that is if we only are stuck with the current PoW algorithm.
