There needs to be some way for a user to be able to see something either online or, for example, out on a vendor's stall selling soap or honey, and go to it on their browser. The only thing I can imagine that's simpler than that is a QR code, but it requires you to have a phone that has a good camera, which isn't possible in some places that are developing because a phone is kind of expensive, whereas a URL just requires a pen and paper. A simple URL can be remembered without writing it down, like "blog.google". I will be surprised if URLs go away completely in the next 50+ years, but a new way to verify the identity of the website will probably be developed, if it's necessary.
