Maybe he just dislikes the name, Kennedy, being a part of a toponym there in DC. Kennedy family was\is very influential and the assasination of JFK is one of the most known historical events about the US, and RFK still rolls on it. He probably wants that for himself, and to control what as the wiki-page implies is an american culture. Or maybe he is taking it to mess with RFK in some way? I don’t know.
I’m not sure what he’d probably do, maybe add a map of US plus Canada’s territory and print AMERICA so even dummies would get rhetorics behind it. But what I’m sure about - he’d sell these flags like hotdogs on every street corner, and also add a law that this particular flag can’t be messed with and should be shown instead of the real one.
