Why wouldn't the consumer care about that?
I'll expand on another commenter's analogy. Imagine if it was possible to easily duplicate, atom-for-atom, the Mona Lisa. How much would a copy go for? Maybe $50 with a nice frame? Nothing close to the mega millions for the real thing.
This means that the value of the painting is not the painting itself. It's valuable because of who created it and the history surrounding it.
It's possible that bad actors will try and sell a forgery, with paintings as well as for NFTs. That doesn't mean all paintings are worthless. It just means that buyers have to be careful.
There are plenty of valid criticisms of NFTs (and to be honest I'll probably never buy one) but this is not one of them.
