Also there's the "nothing at stake" problem where forgers can vote for multiple blockchain histories.
There's no definite mitigation to the problem so far, current attempts only rescale the problem, and others just use a POW + POS hybrid.

I find myself having to agree with you, well presented argument but "proof a-b-c-" is just a basis for "Trust" and this runs
against the manter here about "Trustless" network.
PoW is not so bad if it's useful work and not just 20,000 nodes clogging up the CPU and network but that's not whats happening with Bitcoin
but what is happening is CPU-Wars have been created and that only keep Intel rich and the miners competing against each other.
What might had been acceptable if we only had the 1000 miners we needed to maintain the network does
not work when you have 20,000 of more or them and lets save the none debate about the 51% attack
