Depends on method(s), that said, 'seizure resistant' is a bit closer - though, ultimately - again, depending on method - one can, more or less, ensure 'key holder' complicity to gain actual custody - ie. 'Platonic Vault' / 'Plato's Wallet'- The Realm of Ideas/Thought/Mind/Formless'

I guess also relatively quick to move UTXOs to other private key too, which you can't really do with gold 😉
