A lot of these are non-profit or literally extensions of a public library. My public library has a "Library of Things" that costs as much as it does to check out a book. Free, with late fees if you return it late. It doesn't go as far as expensive power tools, but it has some basic stuff folks might need from time to time, like a basic toolkit.

Yes, private, profit-oriented ones will increase prices to increase profits, but thankfully not all of these are rooted in that.
