Hypothetical::So the worst has happened, economic and societal collapse. My family escapes to a bitcoin-friendly (or unfriendly) jurisdiction. I do not have my hardware wallet. Before fleeing I smashed it to pieces, least it's confiscated. Seed phrase memorized and ready to go. Now what?
Now first try to get the basics,in this new hypothetical country/zone that you evacuated you try to find food and shelter first.You wait patiently that the society starts building up again and only then restore your seed to a compatible wallet that will support the seed of your hardware wallet,mostly nowadays are BIP39 so any of them would do.Note that here hypothetically I am hoping for a rebuild first and that not all the world has collapsed but most of it.
