Makes you wonder. They had isolated 10 suburbs as part of the latest outbreak, but what the heck, lets shut down the state border just to play it safe. It's "one-up-man-ship" by the state politicians more than anything - our state is better than your state, your state is a contagion cesspool, we look after our state better because we are better politicians and deserve to be re-elected. The economic pain from restricting trade by doing this and the long term effect on the economy really don't seem to matter to them - they only need to make it to the next election, and hopefully the pain will have subsided by the time of the election after that (with a bit of luck some other crisis will appear so to divert focus away from previous poor decisions).
