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.
Have you installed bugs at all of your neighbors houses or something?
Probably not, because if you did you’d be more annoyed at people who play their instruments well. That requires hours of boring exercise that don’t sound well at all. And even when they practice a piece, they’ll usually practice 4 bars on repeat, for an hour.
