But it is this way, so what's your point?
We can wish all we want for things to be better, but we have to start reopening no matter what. The economy will collapse if we don't. We are out of time.
There's a middle ground between "no attempt made to mitigate the loss of human life" and "safe and effective vaccine readily available". We can and should be doing more.
It's also not too late to do more.
But instead, we seem to be adopting the nihilism that I read in your original post, that, (in a few ways) time's up.
Some individuals/business-owners doing what they can to mitigate loss of life caused by the reopening of their businesses, yes. Some people are wearing masks.
This is by no means universal. You don't have to go far to see videos from Vegas, or of airlines not enforcing their own mask policies.
And also, as a society we absolutely are not doing what we can to mitigate loss of life even within the parameters of a fixed amount of economic activity.
