It's in your own summary, in your own words:
> * it is easier for a monarchy to initiate administrative efficiencies than a democracy, therefore great care must be taken to design administrative policies without inadvertently introducing popular sovereignty.
Wilson believed in "scientific governance" over popular sovereignty. He was unpersuaded that America's diverse electorate could efficiently govern itself, so sought to institute an administrative state to manage the electorate. These paragraphs in Part I are revealing:
"Even if we had clear insight into all the political past, and could form out of perfectly instructed heads a few steady, infallible, placidly wise maxims of government into which all sound political doctrine would be ultimately resolvable, would the country act on them? That is the question. The bulk of mankind is rigidly unphilosophical, and nowadays the bulk of mankind votes. A truth must become not only plain but also commonplace before it will be seen by the people who go to their work very early in the morning; and not to act upon it must involve great and pinching inconveniences before these same people will make up their minds to act upon it.
And where is this unphilosophical bulk of mankind more multifarious in its composition than in the United States? To know the public mind of this country, one must know the mind, not of Americans of the older stocks only, but also of Irishmen, of Germans, of Negroes. In order to get a footing for new doctrine, one must influence minds cast in every mold of race, minds inheriting every bias of environment, warped by the histories of a score of different nations, warmed or chilled, closed or expanded by almost every climate of the globe."
Wilson's ideology was an outgrowth of the political situation in which he found himself. He was a WASP in a political party dependent on massive numbers of Catholic immigrants for political viability. The administrative state was a way to maintain WASP control of the government while leveraging the votes of non-WASPs. That's something that has persisted to this day. Federal government agencies, particularly the intelligence agencies and foreign service, are the last bastion of WASP America.
