More people would try playing an instrument if they could borrow one to try it out. I already play several, but I’m running out of money and space for more. It’d also be nice to pop down to the library and check out the one I’m currently obsessing over to see if I want one permanently. Hell, I’d donate ones I hardly ever use to add to the diversity. This wouldn’t replace buying instruments any more than regular libraries ended book stores.
Obviously your mileage may vary based on where you’re located, but look into makerspaces in your area. There’s one about 20 min from me with a fully equipped wood and metal shops, CNCs, pottery wheels and kiln, electronics benches, etc etc etc, as well as like, 4 others within an hour drive. A ton have workshops / knowledgeable staff on hand.
