Also, why bother with individual private keys nowadays when we have seeds and seed words that are much easier for humans to write down?!
Let me play devil's advocate: I still like the appeal of a nice looking paper wallet. In a way, it's the only "collectible" I can create on my own. It looks good, and when created properly it's 100% a cold wallet. If you want to fund the 12 words you wrote down, you'll first need to derive an address on a secure air-gapped system again. A paper wallet simply shows the address to send to.
