I admit I missed that. But backing up your self-hosted wallet is way less technical than rolling your own Dropbox, so I don't think it changes my argument.

I have family members that have done the following:

* Email me photos because they don't know how to add them to a shared google photo album.

* Aren't on Facebook because they can't figure out how.

* Forget their email password so just made a new email account.

* Make a different decision on iOS vs Android every time they get a new phone.

A very large segment of the population behaves in this way. How will self-hosted hardware wallets work for these people?

What do you say when Grandpa calls you (because he doesn't text or email) and asks who to call to recover the money he was defrauded of?

I have family members who paid for computer service because Microsoft was so nice to call them after detecting an issue with their computer. But lets get them all cold wallets to hold their money.

And those people should use social recovery wallets, as I've mentioned several times above.

As for Grandpa, I hope he doesn't have a checkbook.
