Let's be real, Trump strives on panic. His whole modus operandi is to make the world seem as scary and turbulent as possible. See his comments on Antifa, Mexicans, immigrant caravans, MS13, liberals will take all your rights, etc. He creates panic at every opportunity where there is none.
No matter how you slice it, "reducing panic" was not the right move. Most obviously the Trumpians follow every word he says, to this day people are regurgitating false comments such as the "death rate is minisculy low", "seasonal flu is much worse, those Dr's that worked their lives to be experts, they don't know anything", etc.
Was he doing it to punish the blue states that were hit hard early? Was he doing it to perk up the economy? Was he doing it to make him look strong amid chaos? No matter the reason, the results speak for themselves. Many deaths, cases, and enduring scepticism of covid and any measures taken to control it.
I really can't think of any way to spin his reaction in a positive light.
