why does it have to be hazardous duty at all?
as long as its not service to the state as the only option, because I would oppose that with every fiber of my being
I’m paraphrasing, but the reason the duty had to be somewhat hazardous (according to Heinlein) is to proove you would put the good of society ahead of yourself (a good test for politicians-if it sticks). They also accepted non-military service but given the subject of the book there wasn’t as much detail given to those positions.
The main difference is in the government itself. The government served society, not the other way around.
