What should the government do for the citizens?
Protect us from asshats who want to do harm. (police, Courts and jails)
Protect us from foreign militaries. (Army/Navy/AF)
Protect our borders. (proper border guards)
Have some system to know who owns what land. (some sort of land management scheme)
If the new nation is coming along nicely then start adding the superfluous stuff like libraries and public schools and organized fire protection and new roads and keeping a list of people who can use those roads. If things are going REALLY well maybe start adding the super superfluous crap like catastrophic medical insurance, protecting other friendly nations, etc.
uhhh...everything else?
