Open state borders…for trade and tourism…is all very well. We want trade and tourism; ie. we want money, and we want someone to bring it to us. But presently there is a chance that they will bring disease and death to us.
Not that this was not always the case – tourists can murder locals as easily as locals can murder tourists – and interstate commerce can impoverish as well as enrich. You just have to have the control knobs set the the right way to gain and not lose.
But now tourists can bring in a disease we cannot yet cure. It is in our interests to keep them away, and to stop ourselves from going to their homes and risking the same result. We, and they, are going to lose the chance to exchange money ( and that is all the trade ever is ) but we also give time for science to find a cure for this disease that haunts us.
We can exchange canned goods and television shows and chilled mutton. We can send disinfected parcels back and forth. Let us be content with that and wait out the cycle of disease and cure. And let’s remember where it all came from. We can’t fathom why, but we can reduce the chances again.
