It's incredibly disheartening that you hold this opinion. By requiring that people obtain the full rights of citizenship only through service to the state, you would be creating a massive self-feeding bureaucracy, ripe for tyranny by the state, and oppression of the people. Those that have a stake in the power of the state will seek to keep it running, regardless if it were just. You would be creating a class of nobility, and inviting ruin.
We don't often agree, but I completely agree with this.
