OK, I think I finally understand what the hell an NFT is.
NFT WTF FAQ.

Very simply, an NFT is a work of art in digital format. People buy and sell the digital art with cryptocurrency like traditional art is bought and sold with real money. Old game, new twist. Do any of us know anyone who has ever bought an NFT? Do any of us know anyone who has ever bought a piece of original fine art of any kind? No harm in putting your creations up for sale as an NFT but I'd put my effort into work that has a commercial application. Not that an NFT couldn't satisfy the needs of a commercial application, just people with commercial art needs often have a lot of specific input they want to have addressed by the artist.
Back in the 90s, there was still work for "illustrators" ...people who made custom art images for commercial application. Then somewhere around '95, illustrators started making images speculatively and selling the use of those images inexpensively to any number of people. The illustrator would think about what kind of image would work well for a specific application and then set to creating that image with the hopes that a lot of people would find it useful. Stock illustration, it was called. You pay fifty bucks, you get ALL rights a digital file of an image that would have cost you thousands of dollars if you custom ordered it and paid for whatever rights you required use of. The catch was, someone else will buy that same image for fifty bucks like you did. ....but it was so cheap, so what! You were allowed to change the artwork yourself and computer technology made that pretty easy. This spelled the end of the career known as illustration. Somewhere around 2000, there was such a glut of stock illustration, there was hardly a need for illustrators anymore. You could buy a DVD of fifty stock images for $50. Of course, there's still a need for unique art in commercial applications but the bread and butter everyday work is gone. There's no need for it anymore. At least that's the last I heard. I was out of it by 1997. Actually, just about all of the work I did was highly specialized and most of my clients would not have tolerated the possibility of anyone else using the same art they were using. I don't think stock illustration could have replaced me. The problem was finding enough buyers with enough money to pay for it. I couldn't do that after 5 years so I gave up. That's why I became a teacher.
...but now that we've had a digital wave to ride for the last 25 years, I might just jump on that band wagon. I suspect the challenges would be the same but there's no point in going back to traditional techniques to do commercial art today. Maybe I'd try some NFTs. It's still just a fine art game as far as I can tell.
