One of the dissenting opinions (Sotomayor, I think?) stated that the CDC is allowed to do things like quarantines, and therefore something more benign like an eviction moratorium ought to be allowed too. I found that logic pretty convincing that the Trump-appointed justices were in the wrong. But, right and wrong don't really matter -- just winning.
The CDC is allowed to do what is authorized by Congress within the limits of the Constitution. If that does not include eviction moratoriums but it does include quarantines, then it does not follow that because the CDC may quarantine people it may also issue a nation-wide eviction moratorium.
