Because the one root referred to is the USG/ICANN root. It cannot avoid being political (anymore).
Then you must be reading something into the mentioned document that I don't. As far as I can see, nowhere is either USG or ICANN explicitly referred to in that document.
Oh come on, we're not idiots here, what other root could it possibly be referring to? You're being intentionally dense.
Well, obviously I disagree. It is my firm opinion that the people politically opposed to the ICANN/USG/pick-your-DNS-political-enemy are reading way too much between the lines in this document. I stand by my claim that the document is first and foremost technical in nature, and I wish those people claiming otherwise would actually go back and read the document and cite chapter and verse.
