I personally would be happy with a gradual release of lockdown.
But this is what's going to happen - so who are you arguing with here?
I feel like a lot of these posts are arguing with an imaginary person who wants lockdown to go on until there is a vaccine - a straw man.
Regardless of whether you personally care about the people (healthy or unhealthy) who become ill for a couple of weeks, or those who die, from coronavirus, if there are too many of those ill people at once then all sorts of society's systems will break down.
If there is too much coronavirus circulating, then the illness that causes (even without the deaths) will fuck all sorts of things up.
If there is too much coronavirus circulating, then people will not be going to non-essential shops, to restaurants, cinemas, events - even without a rule telling them they mustn't. They won't be planning big weddings or going on holiday or booking haircuts.
If there is too much coronavirus circulating, then all sorts of businesses will suffer. Routine healthcare won't happen due to all the staff sickness. Cancer treatment will be cancelled. Dentists won't be able to treat people, psychiatric appointments will be cancelled. Bus drivers and paramedics will be off sick, some for weeks.
If there is too much coronavirus circulating, then people with cancer, depressed teenagers, pregnant women - they will all risk being ill with coronavirus at the same time as their existing problems, and facing major problems with the services they need to use.
Our only hope is to reduce the amount of virus circulating as much as we can, and to keep it at a low, known level by testing, tracking and tracing, and social distancing. Lockdown has started that process off. The next stage, as that is phased out, will still involve an enormous amount of hard work by all of us.
Every interaction we have or business decision we make will need to be assessed and tweaked so that it is done in a way to prevent, or reduce, virus transmission. Some things will be easier to do than others. We do have a lot of collective power to make this happen though.
All these posts saying this is ridiculous, it's gone on long enough, we need to get back to normal with healthy people going out and only the vulnerable hiding away - they all seem to assume that it's going to be fine for healthy people to go out because it won't really matter if they (you) catch the virus.
It will matter - the individual risk might be low for some demographic groups, but the collective effect of lots of them (you) being ill at once, and the illness spreading via them (you), will be huge.
There's no way out of this that doesn't involve trying to reduce infections - a policy of generally accepting widespread infections for healthy people is simply not a viable option.
On the positive side, we have a lot of power, collectively, to change our behaviour once lockdown has been phased out. But to do that we all need to remain appropriately cautious about avoiding catching and spreading the illness. We can't go out with the attitude that catching it doesn't matter.
We need to go out with the attitude that avoiding catching it really matters, even for healthy people, but feeling confident that the actual chance of catching it will be low because of the lockdown (initially) and then the testing and contact tracing and social distancing (longer term).
