Of course, the laws and regulations that have cropped up sometimes are in response to the addictiveness of particular vices. That's why we don't regulate shopping for example. It is kind of disingenuous to put "shopping for clothes" and nicotine addiction on the same footing.
I agree with much of what you said. I'm not sure where I'd place Facebook in this case. Honestly, I'm not sure I'd make ruddct's argument for regulation based on the addictiveness of facebook more than I'd make the old anti-trust, money in politics and unchecked influence arguments.
