I would imagine regulations and law enforcement. Catering to such demand usually only makes it mainstream and greatly increases it. The divide between those who care and those who just want to do what they want to do is more or less the same in every field, but difference here is species (niches) once lost can pretty much never be brought back. The stakes are higher when losing a keystone species, say, versus a Van Gogh (just for examples sake, I certainly hope we can preserve both). Yet sadly more people identify with the creations of their own species, than outside their species.
