>We still have public libraries. They usually have a pretty sizable collection

The public libraries in major cities like the New York Public Library have sizable collections. The smaller libraries in the outer suburbs have a much smaller selection. Yes, there's also inter-library loan system for the suburbs to pull from the big city library but there are restrictions such as only having 3 items at a time.

The neighborhood public libraries are wonderful resources but there can be limitations (quantity of titles) that prevent it from being a sustainable substitute for streaming for someone that wants to watch ~2 hours of content every day. My friend tried the public library and it was only a temporary reprieve from the ads on streaming platforms. The library simply didn't have enough content for her to watch.
