Isn't that wiki article just horrible? I've always used a "paper" wallet, stored it properly and never had any issues. I do agree that the name should be retired. It's just an offline backup or air-gap generated private key.
You never have to worry about some kid hacking your device with offline private keys. The only risk is physical access or your house burning down. There are many materials out there that won't burn in a house fire. Get creative.
I wonder why a company selling hardware wallets wouldn't want people storing their funds
more securely, and for free
