it doesn’t matter how it was made once it’s secondhand since it doesn’t support the manufacturer
I suppose there’s people that bought the original item since it had resale value, but I really doubt that’s significant overall, especially at most thrift stores
idk if clojure has really faded though. some dialects have done well (jvm, js) and some haven’t gotten much use (go, clr), but it feels like a reasonable path. there’s a good chance you can tap into a decent chunk of the existing clj ecosystem too
