I think you are looking at this as a black/white either/or issue. I don't believe it is. As I've always said, the political left and the political right want to control people, they just want the control for different reasons. The radical right, for example, want to make sure you aren't having gay sex and the radical left want to make sure you aren't buying an SUV.
The left and the right want to control different things, OK, but what is libertarianism? I thought it was about reducing control. It's on the "less" side of the less/more government continuum. If left libertarians are for more economic control, then are they less libertarian the most control they demand. And the same for right libertarians who are supposedly for more social control. The more right they are the less libertarian they are.
OK, they don't trust those things, but what do they do about them? The more they do the less libertarian they are. So if they are radical left or right, presumably they'd do more and essentially not be libertarian.A radical left libertarian doesn't trust corporations and a radical right libertarian doesn't trust government. They both have their bogeymen.
