I would also recommend copying the keys in a text file, encrypt that text file, make multiple back ups to the encrypted text file then keep them in different locations.
I would not recommend this. By doing this, you have negated the primary benefit of a paper wallet, in that it is completely non digital. This is no longer a paper wallet - rather it is an encrypted software wallet with a paper back up.
it is the very definition of paper wallets that is no longer suitable for the current reality.
Agreed. The terminology is what is confusing people here. Andreas is using paper wallet to refer to "classic" paper wallets, which are a print out of a single private key and address, and I would agree that such wallets are outdated and expose the user to a number of unnecessary risks which I've talked about in a previous post. The current use of the term paper wallet refers far more broadly to any wallet which is stored solely physically and with no digital copies. The paper wallets I use are seed phrases hand written on paper, but I've also seen people use the term paper wallet to refer to seed phrases stamped on to steel plates with no electronic wallet.
