I expect SE doing NFT's will be on new products rather than existing ones...at least I hope is the case, but I figure the logistics of doing it with FFXIV would be problematic for reasons people have already listed.

Hopefully it just means we avoid purchasing whatever games they have that use NFT's. Given NFT's are so divisive, if they find a way then I suspect there is the perceived risk of losing too many players over it where the effort would probably be better placed in adding new stuff to the Mogstation. I suspect the least risky approach is to do it for entirely new products, because they're not technically losing customers and people are more likely to just boycott those games rather than the company itself. EG. when I speak with my wallet, unless the company has done something especially bad then it speaks about the product and not the company and if enough people do it, sale trends should express where kind of decisions impact it. I hope with the NFT's that this is what happens.
