One third of FTX fees were used to buy and burn FTT tokens. This is nearly the same as stock buybacks, and makes it a security, i.e. an instrument that derives its value from the success of a business.
Buying your own imaginary confetti doesn't magically turn your confetti into a stock or into a financial derivative. A stock confers ownership of the firm that issued the stock. These tokens don't confer ownership of anything, and therefore are not like stocks.
Stocks and derivatives are not the only types of securities. I don't really see what you're getting at here.
For most people, the only important part of what you call "ownership" are the cash benefits (buybacks, dividends, and acquisitions). You can see this from the small price difference between GOOG and GOOGL.
