Sorry I meant specifically, you could just sell digital copies of your artwork on shopify, along with a little pdf from you saying "Mattdesl hereby certifies this artwork as edition N of M". What value is the NFT providing? As far as I can tell the only value is that people are willing to trade in NFTs but are less willing ot accept the shopify solution. But they're both equal measures of ownership. Once you've minted your NFT on Hicetnunc you still have to sell it, and that's likely to go via a crypto exchange in exactly the same way that your credit card transaction goes via shopify?
