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.
A nicely designed and properly created paper wallet would be one of the few reasons why someone would be looking to generate a single address and private key. But as you know yourself, it's a very limited use case. The average person prefers a quality software that handles key generation on its own, provides you with simpler backup options, better security, and more features.
Paper wallets and collectibles have their appeal but they are not for everyday use. Still, we have no idea what OP is doing and what he was funding.
