My point is that you wouldn't be able to tell the difference whether any of these interventions work or not. That's the issue. It's of course improbable that none of these interventions work, but it's probable that some do not work.
At the same time, there are a lot of factors that are purely circumstantial, such as weather/climate, age/health of the population, elderly care system. These may have a lot of influence at the tail ends (deaths).
We must not fall into the trap of making post-hoc rationalizations that confirm what we want to believe. We're paying a heavy price with severe measures, if some data turned up that showed that it didn't make much of a difference, that would be a tough pill to swallow.
