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.

But this is useless. The video is available with or without the blockchain. If you have DRM on the video, then you don't even need the blockchain. The blockchain can't actually do anything outside itself, and if you are trusting Metaverse.inc to enforce ownership, why can't you trust them to store it too?

The whole point is that metaverse.inc is not owned by Zuckerberg or Google, but requires consensus to be changed.
