I assume you are the same person that did not want us to lockdown in March, saying it is 'madness' at this stage. So exactly what stage WOULD you decide it is inenvitable?
I would argue the moment has even passed already.
You know what they say about ass-u-me.
And you're talking out of it. 
Look up my posts.
But I can tell you that in the second week of March, I was already working from home, as much as possible. If anything, you may find me arguing that the UK was already too late in going into lockdown, when the numbers started rising.
As the first cases showed up in Europe, it was reasonable to expect that track and trace would work. And it seemed to be working. Until the big spreader events and before we knew asymptomatic people could be superspreaders.
Which is also one of my objections to the current quarantine. It's too short to be safe. And there's no testing associated, as far as I know. Again, I'll thought out, half arsed, token measures.
But, yes, as I said, the moment has passed. That's why it's madness now. Because the virus is all over Europe now.
