There was (and still is) an overfocus on travel for controlling covid, especially when it was clear that it was so contagious that anything but total isolation wasn't gonna cut it. For instance, cutting South Africa off the map because they detected Omicron first (which in turn happened largely because they're excellent at infectious decrease tracking, it's not even clear it developed there). Or when the US was blanket restricting travel from countries that had way less covid cases.
