I have now read numerous positions on these NFTs- The question that doesn't get answered in any of the articles is what are you truly buying? Let me try and define it as I see it, today.
The rights you acquire with an NFT is similar to the day when you bought a CD, Tape, 8-Track,. You have the right to listen, share and show but you do not own any rights too monetize or license that "medium" other than possibly selling the "mechanical" (Cd etc) of it - which transfers only the rights you had when you bought the mechanical. This was challenged as well back in the 90s by record labels BTW, and lost. They did NOT want yo to have the right to sell your CD, sorry tape I meant.
Here is the question. Would you pay 100K or 6 Million dollars for a CD, Tape or 8 track of "Stairway to Heaven" ? Maybe if it was the last one on the planet and no more copies can be made. You would also have to love Led Zeppelin or think OTHERS do and may want the only copy left in existence when you are ready to sell.
NFTs are for collectors to signal they have disposable cash and they want their tribe to know it. It is like any other collectable class or asset. Some of these collectors make ROI most don't.
The interesting part of this is the utility of it and how future works, incorporeal rights will finally have a platform to provide real ownership provenance. The real winners here will be those platforms collecting "GAS" on every transaction. Gas is the fee these platforms charge for a number of services.
Me I will invest in the gas and let the collectors do their thing.
