I think part of what made home searches annoying in the colonial era was that they were disproportionately applied to the political opponents of the colonialist status quo. We see those concerns reappear in the modern day in the form of, e.g. loveint, and presumably other pernicious politically motivated investigations. The federal code is so broad as to be able to be used to harass anyone for a legion of infractions at any given moment, so it is a reasonable threat.
