This is a slippery slope. These policies had a vast affect on the lives of millions of people. Business were shut down. Schools were closed. People were instructed to stay in their homes for years. Simply saying, "Well, we made our best guess," is absolutely not acceptable. When the government curbs human rights, they have an obligation to weigh and justify the costs with scientific evidence.

What is your suggested approach when there is no (reliable) scientific evidence for any course of action and not enough time to gather such (reliable) evidence? Note that not taking any action is also a decision that, in your framework, requires supporting evidence.

Not taking action doesn't require supporting evidence, and insickness didn't propose a framework in which it does. There is at any moment an infinite number of things you could choose to not be doing. You can't collect evidence for not doing those things, as the amount of evidence required would also be infinite.
