Blockchain is the immutable ledger, a place where if someone writes something down, it is guaranteed to not change, the immutable part. The difference between Blockchain/crypto/bitcoin and YouTube, is that the latter puts no guarantees about the content of a link, we trust Google. If you go further, the content doesn't need to be a simple url, it could be data of any type. People get stuck on "who needs to pay for url, when I can copy the contents freely", but you're not buying simple url, you're buying a multidimensional point in the current manifestation of what we think as web3/metaverse. This point is the intersection of your private key, Blockchain used and the content(url). This is valuable because none can claim the same point, and it is guaranteed not to change.
