I hear you but, how does having each State determining on it's own, things that pass freely through and between all States, help the situation? States Rights is a valid concern but when the actions of one State directly impact the operation of another, the States need to get together with a coordinated, systematic approach. In this regard the Federal Gov't can serve a role as a facilitator of this needed coordination and cooperation between the States.
Another example of something that has these attributes is voting processes and I applaud efforts to establish National voting standards.
