The problem is when some states get full of themselves and try to regulate wants to remove the right for local kids to see adult content by pushing complex, unmeetable requirements onto all 50 states. Texas wants to block the other 49 from sending Federally-legal medicines to Texas residents. In general, "small government" states spent a lot of time and effort making other states implement their local experiments.

If Utah wants a firewall, they can erect one at their borders. It's crazy of them to expect everyone else to do their work for them.
