Yup. Remember that well. "Bookstores" were tiny places with fewer books than we had at home. If you really wanted a selection, you'd go to the library. Then came B&N, Borders, etc with vast holdings on par with the local library (or bigger), and - better yet - newer content: everything was new & content turnover was frequent, as contrasted with the library which was pretty much stuck with what well-thumbed old volumes they had. In-store coffeeshops just clinched the attraction.
Local libraries already lend ebooks as well. I'm not sure why more people don't take advantage of that.
Mostly that it's just a new option that hasn't normalized yet. 'til recently, the process was obnoxious enough that physical media and/or a CC# made it much easier to get what you wanted. I'm using Hoopla a lot now; it's improving fast but hasn't quite reached the UX needed for normalization.
