True - but arguably Trump was too slow to invoke it and it wasn't broad enough. And states had to bid against each other to get PPE, only to have the Feds then seize confiscate some of them.
My main point was we should have had a coordinated response. Framing it as "leaders decided to indefinitely maintain crippling restrictions" is misleading. Lockdowns were necessary at the local level because there wasn't a coherent strategy at the national level. (Again, speaking only of the U.S.)
