It hasnt been called a draft but being drafted to stay home is just as legal as being drafted to leave home.
The Supreme Court has ruled only a conscientious objector (to killing a fellow human) has a legal objection to a waver.
Those wanting to evade the home draft are doing quite the opposite, effectively asking for permission to (possibly) put themselves and especially others in harms way.
Nothing is cut and dried of course, just giving outside examples.
