I think, unfortunately, it is becoming increasingly clear that this is, currently, what the government are planning for. Whilst in my opinion from both an economic and social perspective, social distancing is simply unviable for more than the short term, I think it's clear that the government are planning to enforce it, using law if neccessary, for the medium to long term, and worse than that it seems they're planning on keeping it 2m throughout the crisis.
I'm honestly shocked beyond belief that the government actually think this is a viable way to live the next year or two of our lives, a socially distant society has so many cons which in my opinion completely outweigh the risk presented from the virus. It does appear however that, no matter how optimistic we may feel about the fact that it seems unviable for more than a few months, the government is planning on this being a year long (perhaps considerably longer) solution. The two outcomes are that either someone realises the vast economic damage this will cause and changes the direction that the government want to take, or, that we have enforced social distancing for over a year and the economy takes a very, very damaging hit indeed, and I'm beginning to worry that the latter is going to be what will happen.
