Is it fair to label this "extremely authoritarian" though? I tend to agree with Sustein's views as described in your comment (not the views described in OP's comment) but I don't consider myself authoritarian...
Sunstein endorses using the government to do things like increase the amount and diversity of political discussion in society, or decreasing how much people buy fast food and soda, which is pretty far on the authoritarian side of things.
It's not an inherently pejorative label. For example, it's authoritarian to argue that the government should interfere with private real estate transactions by preventing people from discriminating against potential buyers based on race. But most people support laws of that nature.
