And people that are mobility impaired, such that they cannot get across the street in a shorter amount of time or be agile enough to dodge vehicles that behave unexpectedly.

> No one claims NFT proves ownership of entities outside of the used blockchain. But within the chosen blockchain, they do prove ownership of that particular NFT. That's a fact.
what if i steal your private key? what if i upload a different NFT smart contract that gives me an NFT of the same image you have?

First off, images have nothing to do with NFTs and vice-versa. Yes, some NFTs links to images but those are uninteresting and hype-driven (or I don't understand it). Once a NFT has been created, you cannot replicate it as it's a single instance of a token (hence the name "non-fungible").
