Yes, so give me exactly what you do for other medical interventions for lockdowns or masks to prove they work. That is what I've been asking for for years now and still nothing.
1) Lockdowns and masks aren't medical interventions, though, are they? Masks are part public health policy and part personal protection equipment, lockdowns are public health policy.
2) Asking for "proof" in this area of policy is, bluntly,
fucking stupid. It's beyond stupid. It is a demand for total paralysis.
What you are in effect arguing here is that if a respiratory disease arrives that is as infectious as covid but kills 50% of people infected, neither lockdowns nor masks should be mandated because they are not proven. This is not an absurd example: it is genuinely the inevitable result of the logic you are pushing of 'no proof, no policy.'
Your logic can also be applied to literally anything in policy. Raise interest rates 0.5%? Prove it works. Spend another $500 per pupil on education? Prove it works. Cut benefits 5%? Prove it works. All these policies have potentially serious long-term effects, from quality of life up to life itself for millions of people. "Prove it". The only result is a demand for zero governance, because no such proof exists, nor possibly could ever be revealed (after all, once a choice is made, no counterfactual exists to demonstrate what the alternative was), at least certainly not within the timeframe required for the policy to be enacted.
It's a way of looking at the world which is either incredibly stupid or deliberately fraudulent.
