I understand that is the way it is.I think you need to slow down and read.
The commercial side of wildlife is tightly controlled via all kinds of laws, a vast majority of it by the States with a vast majority of the laws being State law. Your worry about the "feds and California" controlling wildlife in Idaho is a red herring, best case, and an unfounded worry. Neither California, nor the Feds, have anything to say about how Idaho chooses to manage deer, elk, bears, sheep, goats, moose, grouse, quail, bears, yellow perch, crappie, bass, sunfish, etc. etc. Further, there is no legal path for them to interfere in, or pass laws, regarding Idaho's management of same...including the sale of antlers.
Any law pertaining to wildlife management in Idaho, is strictly the business of the Residents of Idaho...case law matters, and there is a long legal history of the individual States rights of wildlife within their border. I fully support the individual States to make their own decision and pass any law they see fit to manage their wildlife assets. If Idaho decides to ban the sale of antlers...nobody to blame but the citizens of Idaho.
BTW, the (you) that you refer to is not from California...
I do not care what state you are from, I believe you got my drift.
your ."if only obviously"' implied you do not think that is the way it SOULD BE. if that is not correct ,please clarify
