I just joined a tool library in my neighborhood ($1/day for power tools), but thought to myself, why doesn't my library have a room (and staff member) for this?
Other things you can borrow or use in local libraries: cargo bikes, moving trolleys, sports equipment (tennis rackets, skis, skates...), board games (never had a single missing item in any I've borrowed), 3d printers, laser cutters, music rehearsal and recoding studios (with grand pianos), tents for camping, tablets and computers, musical instruments, etc.
I think this is great because it makes these things available to the less privileged and I don't mind paying the taxes to support this.
Getting to try a 3d printer in the library (this item you can't take home, or the grand piano for that matter) may be a life-changing experience for that less privileged kid and give them the opportunities for better life.
I grew up less-privileged in a lousy neighborhood in the 1990s and have to thank my local library for all the programming books, computer and internet access and magazine subscriptions in helping me eventually get a degree in Computer Science and become a professional in the field.
But you are not alone with your opinion, there are plenty of people who think "libraries should stick to books" or "shut down libraries, no-one reads books any more". I choose to politely disagree and say "borrow all the things".
