US dollar payments aren’t subject to the approval of stakers, and existing PoW miners have no on-chain mechanism to prevent new market entrants from competing against them for hashrate.

So, “no”.

To begin staking, you first need stake. But merely transfering a PoS coin from an exchange to your own wallet for subsequent staking is inherently impossible without the approval of existing stakers. Even this isn’t enough: existing stakers must also approve of your initial staking transactions.

Which is not how PoW mining works.
