Zoos are already tightly regulated and no, you can’t just put a tiger in a dog pen in most places and call it a zoo. (You could in rural Mississippi, but I’d research any zoo there before going.)
And Siberian tigers became extinct many millennia ago.
The anarcholibertarianfreewheelinifitain’tintheconstitutiondon’t”f”withme crowd would hate to hear about “tightly regulated” anything.
