If the computer is in even a marginally secure place, storing passwords on physical paper is better than what a lot of people do.

Of all the proverbial bullets I've been hit with, none had my name on them; they were all addressed "To whom it may concern". The times my identity has been stolen or my accounts compromised it was because somebody attacked some fairly large entity, like Alphabet or Equifax or Microsoft or Visa. Nobody's going to walk into my house looking for my passwords. They might walk into my house looking for my television, but that hasn't happened to this house longer than I've been alive.
