Re: Presumably....
Yes, you absolutely can and there are definitely cases of people creating NFTs for things they have nothing to do with and making bank already. There's also nothing stopping multiple NFTs for the same thing. At the end of the day an NFT isn't proof of anything at all and has no useful value at all other than reselling to the next sucker. They're the virtual equivalent of a void replica deed to a property.
Also because creating an NFT is significantly more complex than creating a cryptocoin they're many, many times as environmentally impacting to boot. The average NFT emits as much carbon as a cross country drive, and the more they're bid on/transferred/sold the worse it gets, it's not just at time of manufacture but continuous and forever.
I saw someone describe them as an ecological nightmare pyramid scheme, and that's pretty much right on. At least tulip bulbs could be planted into tulips.
