But again, the interesting thing is that you can buy up 51% of a PoS coin, and then sell off your coins so that you no longer have 51%, but your history of having once owned 51% makes it possible to attack the network at any time, for free.

I doubt it.

The other attacks you describe all derive from the fundamental reason I declared all non-proof-of-work systems to be insecure back in April.

My logic was mathematically fundamental. The input entropy set is quite deterministic and well known and thus can be preimaged. For example, accumulating a lot of coin-days-destroyed and then targeting them in clever ways to subvert the security.

The randomness (entropy) of each proof-of-work is fundamental and mathematical and it can not be preimaged. It can only be surely defeated with > 50% of the network hash rate.

Anyone seen Anony Nakamoto lately ?
