Brain Fertilizer

Perhaps not, but it's still a good default answer until someone demonstrates they have a better one.

Well, I do think a free market solves most problems, or perhaps, solves most of all problems. I'm also convinced the problem is just that most to all of humans are dolts, cads, and idiots.
Most of my arguments are with the assumption that libertarianism is attractive and sounds pretty good, but breaks down in the same place communism does: basic human nature.
Here's the main test: libertarianism assumes that people will control themselves more effectively than the government can. But how many a$$clowns have you encountered over the past year....and how many of those people actually considered themselves to be a$$clowns? The person you think is the biggest jerk in the world probably has as many friends and loved ones as you do. And we can't even stop people from driving on the shoulder (or closed lane) for as long as possible to merge right at the slowdown point...so how can you expect to get the 80-90% of the population to agree to control themselves well enough to make libertarianism work?
In that, a free market is like democracy: the worst system in the world, except for all of the other systems...
The only reason for this post is to remind people that even free markets aren't the perfect solution to every problem. Government does have its purpose and uses...although I will agree ours has far outstepped those bounds long ago, particularly under FDR and LBJ...
