People will always figure out ways to distinguish one thing from another, if that's what they choose to do. It's not just a technical problem, it's a social one. We have to make it clear it is not okay to regard ivory hacked from the face of an elephant as better than a synthetic polymer. To regard diamonds scrabbled over the blood of Africans as better than their synthetic equivalents. To regard the flesh of tortured chickens as better than synthetic meat replacements. And this can be done. There is now a consensus that it's not okay to regard the fur of tortured animals as better than synthetic fabrics. Sometimes there is actually such a thing as social progress.
