That's the big question. Will there be any cultral shift in recognising NFT's as legitimate signals of "value" after the hype dies down? You can stretch the hype train out by convincing some big brands to get on board, this will push the price up just by force of recoginition but are the fundamentals sound for what values the NFT? as like you say, there's no real scarcity and we still rely on meat space for settling real disagreements about ownership.
