You wrote all that out and didn’t really think about what you wrote, because you actually proved my point. Yes, they are the same thing, but the difference is one has no value (a digital picture of a monkey) and one has value (a stock in, say, Apple). UNLIKE FTX - the tokenized securities that would be verifiable would be issued directly by the company, so each stock the company issues is done so as an NFT token. You can verify whether it is the company’s actual stock or not because it is an NFT, so it would be traceable all the way back to the company and its initial issuance.
Consider what it is like buying one share of Apple today. Think about it. If you buy one share of Apple from Schwab or something, how do you know you actually received on share of Apple? It says you have one share on the Schwab site, but you are just taking their word for it, and they are taking their brokerages word for it, and they are taking the market makers word for it, and they are taking . . . . In fact, in most cases you don’t even own that stock (you can find out based on how you are taxed when the company issues a dividend - if it is a qualifying dividend, but you owe normal income taxes on it, congratulations, you never even owned the share). Our entire current “mainstream” stock market is based on beneficial ownership, which is the biggest “trust me bro” in history.
However, if the transaction was done on an open, distributed ledger, it is wholly verifiable. NFT goes directly from company to each owner and the entire transaction history is visible, verifiable, and instantaneous.
