The future has to be looked at and potential situations that may rise.
The cold hard reality is, lockdown for any serious length of time can't happen, it will cost too many lives. If for argument sake we can close down the world for around a year/until this virus dies or mutates to low risk and still have a healthy situation to come out of it, ofcourse I'd be firmly on board with it no matter what but that won't be the case.
Okay then, let's say for argument sake we lock down till the virus either completely dies or heads to very low risk, and for further argument sake let's say that takes a year.
The world reopens with 60% of businesses gone (and let's be clear, that's a wildly optimistic estimate), who pays the taxes that keep the NHS running? Who pays the taxes that keep the many many families who can't find a job because there are none fed?
And I'm not "apathetic" about the deaths that will occur, not least because at some point a lockdown will actually start causing more deaths in the moment too, get to that in a second. I've already said I'm on board with the measures at the minute, it's just not remotely sustainable for this to be a long term thing. Even factoring out the devastating long term effects, hospitals will at some point while the virus is still prelevant be inundated with patients who attempt suicide, are victims of domestic violence, come into complication due to severe stess etc (all of those things are going up already) and that will keep rising further while the country are on house arrest, what will that do? Further take away staff from Covid areas, take more ventilators so someone with the virus will be denied it, in others words totally defeating the object of lock down in the first place.
I want in a perfect world no lives lost atall but tragically that's not possible, so the next best thing is as many lives saved as humanly possible, a lock down for any serious amount of time won't be how that's achieved.
I fully agree with the measures presently because at this moment in time they are protecting the NHS and saving lives, but it will get to a point where it starts doing the complete opposite, not just in the long run but the immediate present as explained above.
