Just like you could imagine whoever needs to move 1 billion dollars would have a decent hashrate so as to not being taken hostage.
It's an imaginable thing; but having to own your own hashrate to transmit money would be a wholly new paradigm, and is nearly isomorphic to simply paying the ransom.

Agreed, this is a new paradigm. My prediction is that nation states, corporations, central banks, high net worth individuals etc will all participate in mining, in order to avoid censorship or attacks on consensus rules. Increasing decentralisation further as a result. Like clockwork.
