The 0% PoS attack - possible?

[monsterer]

Why isn't this possible in a PoS system with bonded stake?

1. Short the coin
2. Pay 100% of on-line stakers to transfer their stake to themselves in one common block (12 o'clock midnight, for example)
3. The chain auto DoSes itself as no blocks get produced until the stake bonds again post transfer
4. Profit

How extensive is this damage? Can the chain recover at all since no blocks can be produced?

Point 2 imho should be really hard to not possible to archieve.

The blockchain would stop until new stakers come online.

You could as well pay all stakers to turn their computers off. This is the same as asking “what if I paid every proof of work miner to stop mining?”, except that stakeholders have lesser incentive than miners to contribute to a crash of the coin they hold.
