I'm suggesting absolute czars have absolute authority over things they are czar of.
No, you are suggesting that the utility-ness of a thing is not a function of whether it's infrastructure requires municipal approval to install, and whether a municipitu can support or approve multiple such infrastructures.
The regulation applied to a thing, to be just, must reflect some underlying principal which serves the public welfare, and if the public welfare would be served by a regulation, it is unjust to not implement it.
To that end Obama is not making a declaration, he's merely making an observation of a transcendent fact: broadband networks are utilities and ought be regulated as such.
My comment is entirely about law and the separation of powers we have in our constitution.
If you can point me to exactly where Obama has the constitutional or statutory power to deem things (or at least this thing) to be "utilities" you will win the day. All other rhetoric is wasting time.
