Presumably the Congress’s power to provide for an Army and Navy, as explicitly set forth in the Constitution, allows conscription for military service.
I would like to see the Constitutional provision that permits Congress to conscript for non-military service. I can’t think of one.
The logical question is, of course, where would this end...why not everyone from age 10 to 80, and why for 2 years. Make it 20 years.

(b) The classes of the militia are - (1) the organized militia, which consists of the National Guard and the Naval Militia; and (2) the unorganized militia, which consists of the members of the militia who are not members of the National Guard or the Naval Militia.
I'm certain that Nancey & Harry could manage to mangle the Interstate Commerce Clause into covering it.
Sadly, that ISN'T sarcasm.
