There are 15 million items offered for sale on OpenSea, for example, and each one of those will have cost the artist $50-100 in fees to list. Almost all of those will either fail to sell, or will sell at a loss to the artist. So, although the crypto-rich want you to believe you're democratising finance or sticking up for the little people against "the elite" or however they phrase it, the reality is the exact opposite of what you describe, i.e. NFTs are moving money from the hands of the artists to the crypto-rich.

"These numbers do not show the democratization of wealth thanks to a technological revolution. They show an acutely minuscule number of artists making a vast amount of wealth off a small number of sales while the majority of artists are being sold a dream of immense profit that is horrifically exaggerated."

Most artists aren't going to sell, in no small part because there are a LOT of artists out there in the world and because selling art is Hard. I've met plenty of folks that spend more time selling art and being social enough to sell art than they spend actually making that art. And this is just the average seller: Few can actually make it a career.

Money, connections, luck, and a lot of social labor are pretty well required to get your art selling at higher prices, and might get rich folks to buy your stuff.
