"I don't like this thing therefore it's stupid." Clearly you've never built a keyboard or shot a gun, there is plenty of physical and mental challenge if you want there to be. I've never gotten into knives but there's absolutely a huge physicality aspect if you go down the self defense rabbit hole there - huge in certain martial arts. But regardless, not everything needs to be a challenge and not everything needs to have "cultural or aesthetic enrichment" (although I'd absolutely disagree on your assertion there's no aesthetic component to keyboards or firearms). Feeling the need to diminish what other people find joy in is the hallmark of a sad person.
