I'd guess that most buyers of objects made from rhino horns are more interested in its rhino horn nature than its keratin composition. If keratin became suddenly abundant, I doubt it'd impact the rhino horn market very much

I know nothing of that market though, could be entirely wrong

But good counterfeits would crash the market. It’s already run by crooks. They’d be happy to cheat.

I also know nothing of it, it's just a fun thought. In a previous life I really enjoyed faking parking permits and IDs and transcripts and stuff... it would be pretty fun to return to that but this time be one of the good guys: faking rhino horns for the sake of protecting actual rhinos.
