There very much is.

For starters, should things actually go south, they'll send you to war. I don't want nor plan to partake in this festival of turning people into slabs of bloody meat. I'm an aggressively pacifist civilian, and fuck everybody who tries to turn me into a soldier.

Second, no work should be mandatory. Turning it into a "duty" is essentially stealing my autonomy and forcing me to do things against my will. This is institutionalized slavery.
