Couldn't you just encrypt your home directory? Or even the root FS entirely.
Either of those should be a must on a portable device storing valuable
information.

But by analogy, would you say that SSH keys and PGP keys don't need protection by a passphrase?

Yes, I will say so. I (almost) never use it, it is either too unsecure yet cumbersome, so I use separate devices (nFA), encrypted FS, etc. where needed. Or nothing at all.
