As some one who is admittedly ignorant how our system of economics works, you seem rather assured that all these unnamed experts know what they are doing and some how are able to centrally plan out our economy on a macroeconomic scale on such short notice when all attempts to do so throughout all of human history have failed so spectacularly. It is almost as if you have no facts to support your argument and are relying completely on appeal to authority. Pay no attention to the economy crumbling around us, the government is here to help.
You are correct! Economics isn't my forte, so I rely on millions of people who do understand economics to create economic policy. I don't understand 100% of the Bitcoin code, so I rely on all of the other people who understand it to point out if there is a problem. What you call appeal to authority is just how humans overcome the fact that we don't live long enough to gather mastery of all subject matters. Every time you drive over a bridge without researching and understanding all of the structural properties, you are by your own definition "appealing to authority" by trusting the engineers who built the bridge to keep you safe.
I believe the government is here to screw us over when it benefits them. If it doesn't benefit them, I have no reason to believe that they're acting dishonestly. Again, it is in the government's best interest to aim for the best possible financial outcome. I do not have the manpower or resources to adequately collect the data to model the intersection between financial damage from the shutdown and projection of financial damage from unchecked Covid19. If you do, I'd completely unsarcastically love to see your predictions. I don't wholeheartedly pledge my allegiance to the government, I acknowledge that it has the ability to coordinate efforts between large groups of people that do know what they're doing to collect the data necessary to make a plan. The entirety of your point is that we shouldn't trust the government because they're the government. its somehow a bad thing to listen to people who have expertise in something you don't.
