The guy in the video says: "You don't really want to be relying on regulations, we learned all the way back in 2009 that those subsidies can be removed anytime." What exactly do regulations have to do with subsidies? Aren't regulations the rules of the game where a government is keeping an eye out over an industry? If there are subsidies involved, aren't these separate from regulations? Are we seeing here a conflation of regulations with subsidies and therefore a message of "regulations are bad"?
