> The CDC wants a say in how people live their lives and thinks they know better than individuals about risk tolerance and decisions
The CDC primarily exists to address collective risk with collective decisions in the face of public health and especially infectious disease events where the dynamics are inevitably collective.
Sometimes collective decisions curb individual freedom -- like curbs literally do, along with a host of related automotive policies one could use as analogs. Criticizing the CDC for "wanting a say" is like criticizing any other area in which collective government wants a say: it's fine to talk about limits to what government should be able to require and what would constitute a compelling reason for doing so (and in fact, that's what citizens of a democratic republic should do), but speaking as if it's a threat to "want a say" in general is unbalanced.
> And they seem to think they can have unchecked power by invoking "science".
Whether they decide to make their decisions on the basis of science observation and study or not, no public institution in the United States has unchecked power, there are always avenues for feedback and change, especially if you have a point that other people find persuasive.
And personally, I'd prefer most institutions made their decisions informed by scientific efforts, which would make them accountable both to fellow professionals in their field and other democratic institutions.
Data's a part of scientific efforts.
