Travel restrictions bought Taiwan and South Korea lots of time in the beginning. Other countries who usually follow scientific guidance have implemented them (israel).

There seem to be no real papers linked to the base of this guidance, except that they feel like a attack on the freedom of movement for a globalist elite and the tourism industry. I rather prefer to be healthy and safe, then to put a blind eye to some elite favoured cultural blind spot.
