Terrible analogy.

The library everyone built is still there, free of charge for everyone to use.

What AI companies have built is an assistant who has photographic memory and has read everything in the library.

You’re still free to use the library to find what you want, but the library is not using the Dewey decimal system.

You’re also free to build your own knowledge base using the information from the library if you want to, and charge for access or give it away for free.
