I agree you don't need a plan for everything. The whole of Manhattan Island gets fed every day without any master plan. Free market conditions allow all those millions of people to eat without any government master plan (of course there are health regulations as a checks-and-balance system... thank god).

But I think the OP point was to assess the mind-set of the libertarian... and their views on Government involvement.

There is a great book (for the life of me I can't remember the name) about the auto-industry.

It takes a look at how the car lobby really screwed over America. Before cars (trains and trolleys) it was the manufactures responsible to provide the method of transportation: i.e. rail-lines, cables, ect.

But somehow... the car industry duped tax-payers into footing the bill.
