If a US court rules they have jurisdiction, then it won’t matter that the defendant is not in the US. Enforcing monetary penalties is also straightforward: since centralized stablecoins like USDC can be blacklisted on a court order, simply being globally dispersed is not as unassailable a defence against legal threats as some seem to think.
To be maximally clear, since it seems to be necessary in this thread, I’m not making a “threat”. I’m simply pointing out that legal action is a real risk that should be managed.
