Regardless of your points, (which ARE true) the fact remains that in todays’s world, (without mashiach being here) without the IDF, every Jew, Chareidi and frei, would be exterminated.
Thus the very lives of the anti-Zionist chareidim are dependent on the existence of a Jewish army. If they don’t want to join the IDF, they have that choice, but a little hakaras hatov for being able to wake up in the morning (to protest the ‘medina’) is still an obligation.
