My point was to respond to your "what if there's never a vaccine? Will we hide in our homes forever?"

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.
