Not really.
If it works! If it does not, in fact, work, no sample of any size will show that it works.
It's unfortunate, but a lot of what we're trying right now will turn out to be useless. One or two recent analyses suggest that the (far more expensive) lockdowns might turn out to have been almost useless. That doesn't mean that trying them was the wrong thing to do.
We're living in unusually uncertain times.
The first three look useful, but I'm not sure if they improve the chance of survival too much. You need some time to find them and enough room in the boat, so it is a trade off if they are useful at all.
The OP is basically arguing for a "something must be done and this is something" reasoning.
