Maybe you could debate when the federal government put it there, but they did. I think we would both agree that at all phases of a quarantine the Federal Government has supremacy over the States.
Further, Federal government deferring to the State on closures is unrelated to their deferment on opening (legally anyway, the political reasons are likely the same)...In other words just because the federal government deferred to States on closing, doesn't mean they couldn't jump in at any time. In fact with the openings they federal government implemented "Opening Up America Again" which is voluntary, but they could have just the same made it mandatory.
Otherwise, You are highlighting many other failures, which I tend to agree with...which are likely part of the desire for the federal government to distance themselves from any fallout of bad outcomes from reopenings. And rest assured when a State opening outcome is good Trump will pat himself on the back and claim they closely followed "Opening Up America Again" guidelines/phases, and States with bad outcomes failed to follow the same.
