On 1, you're somehow conveniently ignoring the "without permission or interference from a third party.". I never mentioned against a car, stock, or house. Nonetheless the functionality still exists. Using ETH or other crypto assets. It gets so much easier. Have you tried it? No talking to advisors, no documents, no discriminatory requirements. Pretty much 1 click and 30 seconds. Fully expect the next question of validity "aha! Well that's against a useless asset!".
2nd example. Yes it can be a hyper link or a hash, is there something particularly wrong with that? The use case I described has still been achieved, it's a digital object. Are you really questioning that people exchange assets using a digital identity? I'm not sure how that invalidates the use case.
By the way you're incorrect that digital objects don't fit on the Blockchain. First it depends which Blockchain. Second, there are some objects that do fit. Look at ENS. A domain name, address mapping fits on the chain. That is an NFT. That exists today.
