That’s just called a database.

That's the rub. Eventually blockchain will be useful for tracking ownership of things like land and cars, whose current ownership is tracked by an analog token minted by a a validator and stored offline (which is to say, the government has a piece of paper on file). I recently bought a house, and I had to buy mortgage insurance in case it turns out that 50 years ago someone fraudulently or mistakenly sold this house to someone else when they didn't actually own it, and then I bought it from the guy who bought it from the guy who bought it from the guy who bought it from the guy who bought it from the guy who sold it illegally, so it's not really mine. Blockchain will eliminate that. Game companies mint tokens to represent digital "assets" that they say you "own" but in reality it's the asset creator that can make more of the asset, destroy the asset or deny others usage of the asset (which is the real, functional definition of "own").

I'm still working my way through my thoughts on this after Bored Ape Money Pit but I think that blockchain is one of the infinite number of ways that traditional ownership models are trying to impose themselves on digital assets when it's the fundamental nature of digital assets to be infinitely replicable for a cost so low as to approach $0/per, and to make it very hard to exclude people from having or using these replicas. I work in software. We're getting to a point where the real value in software is in designing ways to stop people from using it unless they've met certain conditions (usually, having paid for a license). Most of what I do is authentication and authorization. That is to say, determining who a user is and what they're allowed to do. These are external, artificial controls. In real life when you eat an apple the apple is gone. When you and your family live in a house, that house is full of people. When you "eat" (or in some other way extract the value from) a digital apple that apple can still be there. An infinite number of people can exist in one digital space via instantiation without ever having to acknowledge one another. Digital assets defy exclusivity, and without exclusivity their can't be ownership. So what we end up with is a million people who have the same bit-for-bit perfect picture of a monkey, but one guy who has a certificate from the monkey picture center that says he's the "owner" of the monkey picture when ownership doesn't really confer any rights, privileges or abilities that everyone else didn't already get for free.
