I assume you’re aware, but for clarity: it’s not possible to sic the bitcoin network on anything, even cracking sha256, which it uses internally, due to hard-coded ASICs that incorporate specific quirks of the proof-of-work.
It seemed like the reason to use the Bitcoin network in the discussion was to form what a theoretical nation-state actor might possibly be hiding based on the traits of some thing in the physically-existent universe (instead of discussing things completely in imaginary-land).
