This is just another teenage rebellion movement like Libertarianism. "Don't trust the old people. They're just trying to oppress you!" Yes, Libertarians, you are now the old guys who can't be trusted.
Yes, the baby boomers are now all over thirty, but they would probably be considered liberals not libertarians. The movement that spoke of don't trust anyone over thirty was the hippies. The phrase is credited to Jack Weinberg.
Having open bids and only one "bidder" is actually different than sole source/no bid.
I would say yes and no. You can always write a contract such that there can only be one bidder. You just add restrictions that no one else can meet. Must have thousands of hours in experience building government exchanges would be a good choice.
