I'm not sure I agree with your explanation. Most NFTs are like a title to a house. Like a title to a house, you can: 1. Prove you own it; 2. Sell it to someone. Unlike the title to a house: 1. The party certifying your ownership is not the government, but the consensus rules of a blockchain; 2. The thing you own is not physical, but digital in nature; 3. Your ownership does not prevent anyone from copying the file itself for their own uses. Regarding your point that the object you own might not be consistent: because of the cost relative of storing data on a blockchain, the actual digital thing you own isn't usually stored on the blockchain, but a hash of that file (e.g. [1]). Unless hashing is broken, this is cryptographic proof that the object does remain consistent. [1] https://github.com/larvalabs/cryptopunks/blob/master/contrac... Ed

This reminds me of a discussion about NFTs recently. I caught myself having an opinion without really knowing how they work. So I googled it and only found vague descriptions. Then I looked for an actual ETH blockchain contract that implements NFTs on Github [1], read it, and it was all very simple and clear. (So for me it was "How to Learn complex Things Quickly by realizing they are not that complex at all.") So in some cases I'd put "Read the Source Code" at the top. Code is not quite mathematical notation, but it is a concise way to express something.. [1] I read this one: https://github.com/larvalabs/cryptopunks/blob/master/contrac...
