"Alaska's new law is going to be overruled by Trump."
I doubt it.  America is a nation with divided power, not just between the two branches but also between the state and federal governments.  State governments have general police powers but it is limited to the borders (not including "long arm" statutes) of the state.  The federal government has limited police powers which extends, arguably, around the world.  When state and federal laws conflict, thanks to the Supremacy Clause, federal law wins.  But that doesn't mean that they can violate federalism such as enforcing federal law beyond their limited police power, ie. the federal government an enforce federal substance control laws on federal lands but not state lands if the state doesn't have the same or some corroborating law.
