It's akin to hiding money in your mattress, but less bulky. You could even memorize it because seed phrases are between 12 and 24 words.
So people with money in their mattress and no access to a bank should do an elaborate scheme that ends with "akin to hiding money in your mattress"?
With a treasure map and a cross where the treasure is so your children will find it in need? Then make a movie out of it and become rich?
The original point was
> They do not realize that with that wallet if the wallet is gone so is the money. Wheras if the phone is gone, nothing happens to their money.
Which is just false as a seed phrase is all that's needed if the hardware wallet is lost.
