👉 Your local public library. You can borrow movies and books. Return them so someone else can use them too. Not run afoul of the law. Libraries are great!
Your library probably even has digital access to thousands of movies, books, and songs, so you don’t even have to leave the house!
That’s definitely true for books. I have an ereader and I often use my library account to add books on loan to the reader over the Internet. I don’t think there’s video available like that, but they do have physical media like CDs, DVDs, and BluRays.
Some do have streaming services. In Germany there is filmfriend.de for movies and the NAXOS Music Library. For big productions and everything else than classical music they still loan physical media, but it’s a good start.

Alternatively:

Give your former Netflix and Spotify subscription fees to the Internet Archive.

They are essentially a gigantic, global, public library.
