I really don't think they should shut down parts of economy currently.
For reasons that a) nationally its unecessary currently to have such a blanket shut down and b) I wonder how much it'll drive people back to meeting in households.
I read somewhere that the reason public socialising is considered a better option is it enforces people to SD more due to the nature of it being public.
I like Germany's system of having a case per 100k population cut off. So I'm a LTLA yin shut within that when cases reach whatever they decide is cut off nationally.
I'm sure this would be popular but I'd suggest people get a card or there's something you download to phone to show your LTLA. This would then mean you can enter a pub/cafe etc if your not in a lockdown or high case area to stop pressing it beyond boarders.
Also I'd have traffic lights used a again with clear criteria.
So if my LTLA was on red that means I am unable to enter any pub etc outside of this.
If on amber then can use xxxxxx
If green can use pubs etc in any area.
