Regarding roads; Housing developers already build the subdivision roads. Those who build on land in the country often have to build a drive to the main road. So it would follow that those who want to offer commercial products and services would also be interested in building roads. There is a free market solution for everything, and it would be of better quality, cost effective, and voluntary, only if government would get out of the way.
Yes exactly. Maybe one day I'll do a serious "who will build the roads?" post and list some real possibilities.
