No it's not. NFTs aren't a currency. Currencies make even less sense when dissected, but we use them anyway. NFTs are what people who missed out on bitcoin is the next bitcoin and nothing more. Currencies don't even have to make sense, they just have to be accepted in trade. Crypto is slightly more "real" than fiat, but again, that doesn't matter. They just have to be accepted in trade. If they are, they're a currency. Nobody's feelings or opinions matter.
