>The only investments we need the "gift" of government to pursue are those that we get less value out of than we put into. Or those that need more than one person to implement. An entrepreneur can decide to buy a cab and offer rides to the airport - but there isn't much point unless a million tax payers have already got together and built the freeway.
Entrepreneurs and businesses can hire workers just like the government can. And public works such as roads and bridges also apply to my argument. For example the infamous "bridge to nowhere". A lot of these projects are a waste of resources. If the private sector were in charge of building roads/bridges they would be much more inclined to make sure they were actually needed and good investments.
In my post I reference an earlier short essay on mega projects

Some projects entrepreneurs can't build unless thousands of them get together. Many of these mega projects have resulted in very long term benefits. Hoover Dam, Panama Canal, Lunar Mission, DARPAnet are just a few ideas which entrepreneurs can't possibly tackle on their own, even massive corporate IR&D budgets can't be risked on such endeavors.
