The question is: What for? The mainsteam public has been psyop'ed for a long time, to an extent that they put bitcoin and eth and other shitcoins in one row, calling them "high-risk assets". Psyop'ing hardcore bitcoin devs who hold most of bitcoin makes no sense, while the intermediate layer (the average nostr user) holds so little bitcoin that it's unlikely to cause major changes.

If I were to attack bitcoin effectively, I would target on- and off-ramps in the first place. Having full control over the on-ramps is getting increasingly complicated (people develop decentralized exchanges like robosats and bisq), so controlling the off-ramps might be the next goal.
Australian banks have limited transfers to $10k per month to exchanges - on-ramps are disappearing fast.
Off-ramps will be more difficult because you can spend on gift cards etc. ie. getting hold of Bitcoin you’re generally exchanging cash, getting rid you can exchange tons of things.
Bitcoin’s portability is going to come to the fore soon enough. Likely when other capital controls come in.
