I haven’t looked through the entire thread but the challenge of recovering from a PoW 51% attack is that the attacker still holds ASIC mining power and can re-attack each new fork. The same is not true in PoS where the attacker’s funds can be targeted and effectively depleted in a fork, leaving it prohibitively expensive for the attacker to continually attack each new fork.

See the “spawn camping” description and defence in my prior link.
