If someone has his seed phrase on a steel or titanium sheet, there is possibility the person can lose his seed phrase during war. I mean if a war can destroy diamond which is the strongest substance on earth. Many people have there seed phrase written on a paper.

You keep many papers and seeds in safe secret places.
Crypto is for crisis only way but wait you will see total collapse of system all around world and humans cant stop it because it meant to be.
And what are the goverment protections,? If goverments itself have huge financial struggles they barerly can stay alive yes nessecary services works but anything extra it's extra and times of crisis all the extra wealth will be taken one way or another, less you have wealth outside of cryptocurrency next 4 years the better it is.
