Only in a specious sense. The point to money isn't "scarcity", the point to money is TRUST. You trust that $1 is going to be worth $1 tomorrow, and that it will be worth $1 to the shopkeeper and the bank and your family and everyone else. So anywhere you want to trade for something, you can do it in dollars. It's true that to provide that stability you have to control the supply, so money is "scarce". But only in the sense that the economy it represents is finite.

NFTs don't provide that, therefore they aren't a good medium of exchange. They aren't "scarce" in the way that money is or has to be.

They're also a Tulip bubble, but that's a different thing.
