Reason TV walks through a series of thought experiments about income redistribution. It's pretty much libertarianism 101, likely to please those who agree and put off those who disagree.
One point that the video raises (perhaps the main point) is that the institution of the state changes the way people feel about coercion. Almost nobody would feel ok about personally coercing George to give money to Oliver. On the other hand, if we can put some layers between us and the coercion, we feel fine with it. The state works as a device to desensitize us to the commitment of evil acts.
Again, that is a proposition that hard-core libertarians can nod their heads to. But people who are not in that frame of mind probably won't be persuaded.
