A curious thing to ask the forum/thread: what were the incoming traveller numbers per month? Could any country sustain hotel quarantine for even 25% of that amount. (25% being a thumb suck guesstimation of what activity might continue if we are allowed to leave freely).
The number of inbound international travellers in Nov 2019 was ~ 1.7m. So 25% of that is 425,000 or about 100,000 a week ... about 15-20 times the current cap.
