You're missing the simple fact that Hardware Wallets, while some of them might have the appearance of one, are not just a plain USB stick.
I once helped a friend with a crypto investment, so he asked me what the safest option was for keeping them - I recommended a hardware wallet and sent him links to an e-mail, to which he replied that he already had it at home. Of course, he only had a USB stick which I have to admit was quite similar to the Nano S.
I wonder how many people actually use such USB sticks for their crypto wallets (backups) and live in the belief that they have a hardware wallet?
