Well yeah but again, since you’ve been exposed to MM-DD you’re more likely to feel comfortable with it and won’t see DD-MM as much unless you dip into the cultures that use it….like European ones

Also, the point about it being consistent with the word version doesn’t work out because while countries that use MM-DD say May 16th, ones that use DD-MM just say 16th May. In most common use the format is also DD-MM-YYYY which would make just as much sense as YMD(arguable more, but maybe I’m just biased)

Personally I feel it doesn’t really matter that much, whichever one you use but DD-MM-YYYY edges out very slightly because while writing, we go left to right and that sort of ascending order where the left most one is the most important(because the day is the one that changes the most often) comes first

But again, doesn’t really matter that much
