The term "chaos" is exceedingly problematic. It's used often and haphazardly, but in reality, there's no such thing as chaos. It denotes a lack of order, but cause-and-effect always applies.
I would use the term figuratively to indicate phenomena that plays out on the "negative" side of cause-and-effect (negative meaning undesirable or counterproductive relative to the inherent lifeward striving of living beings). Man's order is chaos by this definition, as (being a denial of reality; namely the reality of man's free will autonomy) it counteracts the healthy, authentic, positive functioning of the natural order.
For (anti) political anarchy to be described as chaos is entirely incorrect. But since man's order is order in some sense (albeit negative order), many believe its absence means a lack of order. Of course, this requires one to wholly ignore the natural order, and thus everything in physical existence (and perhaps beyond), since cause-and-effect order reigns supreme in the universe at large. Far be it from mind-controlled statists to be averse to that oversight, however, as nothing serves their position as faithfully as ignorance.
