URLs can also exist forever. The real point is that they are digital assets that don't exist on the blockchain itself.

The content at a URL can be changed at any time, NFTs that don’t prove that the content that serve hasn’t changed make for worthless NFTs.

IPFS is ideal for this use case because the URL contains a hash of the content meaning that either the original asset is served or nothing (which you can fix if you have the asset).
