There's a lot of stuff that isn't really efficient to own individually. I need a power drill one day a year or less, it's just gathering dust in my closet the rest of the time. I bet most of my neighborhood does the same.

I often dream of a local community center of sorts that lends out tools, and other such things, maybe for a small yearly fee. They could spend to get something robust, good quality that lasts for a long while. And the whole neighborhood could benefit. Sort of an expanded version of a library? I guess none of that is very profitable.
