Funny side note: I had an argument with a random account on Twitter a while back where he insisted that this was no problem for him because he knew Jiu-jitsu (or something similar) so he could just beat up any cop that tried to take his sats😂 I wish I could find that thread for you guys but it’s #NostrNovember so no can do.
Oh they can absolutely take it. If someone knows where you live and knows you own bitcoin, what’s to stop them from breaking in and torturing you until you give them access to your privatekey? The asymmetric cryptography makes it unconfiscatable as long as you can keep your privatekey a secret. The “$5 wrench attack” has happened so many times that Lopp has a overview of all known physical attacks on bitcoiners:
