Going off topic, it can be policed if there is the will, and such quarantines, especially as applied to passengers, certainly are policed at some places I (?you) have been on the Long Haul network in the last couple of months.
The problem is if the UK introduce a quarantine for appearances sake they will get "found out", and that in turn could have implications for us in the travel industry and aviation.
Back to topic..
