Which is easier to pull off, once you have control of the stolen coins?

* Use them to vote for two chain histories, and thereby get the victims slashed?

* Launder the stolen coins, buy an ASIC fab, churn out ASICs, plug them into the power grid, and use them to continuously and sustainably attack a PoW chain for eternity, all while not getting caught?

In case it's not obvious, the first one can be done the second the compromise takes place. The second one takes years.

> Hacking billions of dollars of cryptocurrency is NOT easy, and it gets harder with every passing month, because validators and hodlers have billions of dollars of incentive to protect themselves.

Why should a hodler bet that over 2/3 of the chain's validators will never, ever be compromised? Money doesn't buy invulnerability, and an attacker only has to succeed once at breaking quorum to break the chain.
