With digital content and ebooks, isn’t it possible for even the relative poor to have home libraries?

Back in ancient times (the 70s and earlier), if one had a physical library in their residence, of hard backed, and paperbacked physical books, it leaned to an air of wealth; books were not cheap, even if you gleaned every yard sale. To have a personal library of 500 books represented a lot of money and wealth. Now many books are in digital form and can be kept in a device whose physical dimensions are less than that of a mailbox. That lets many more people have books (in digital form). In theory doesn’t that mean anyone who is poor, if they can afford one of those digital storage/readers they can have a library larger than the wealthy had 25–50 years ago?
