Interesting point though I'd go with another analogy.
You can go to a library to borrow a book, but you can't go to the library and copy all the books for your own use.
You can go to a library to borrow a book, but you can't go to the library and copy all the books for your own use.
It's just impractical to photocopy every page of every book in a library.
Otherwise, intellectual property laws can perhaps apply.
It'd be a hard push to claim it's fair use, a wholesale copying of other's works.
You can actually copy all the book but the things is you can't publish it as your own book after you copied. Because obviously it is not your work.
Why? What's stopping me from doing that? The only limitation is time.
