A court, however, can force you to give up a password or hold you in contempt (which is essentially the rubber hose option)

That remains to be seen; I don't think that there's ever been a definitive ruling on this in the US. One real problem is that they would have to be able to prove that you knew the password, and that can be a real problem. I have an old Tails drive; it's been years since I used it, and I have no idea what the password is anymore. Shit, I sometimes have a brain fart and can't remember the passphrase for my password manager, and I use that a lot.
