Your initial point didn't say it was nonsense though did it you said you'd rather everyone just stick to a full lockdown. The attitude of just because we have to suffer everyone else should makes no sense.No the tiered one is nonsense from what I can see. The social mobility of the population kills the tiered system stone dead.
It was always a nonsense and a sticking plaster on the abysmal track and trace shambles.
Agree track and trace and the way tiered system is/has been handled is poor but the idea of a tiered/geographical split system does make perfect sense.
