The problem I have with boating is that it takes a number of related environmentally irresponsible "wants" and chains them together into a series of linked "needs". One "needs" the truck because they have a boat. That's expected to be the end of the discussion, but really it isn't because it is fair to continue to question the whole chain. People are bad at distinguishing wants and needs, or alternatively people are very good at presenting their wants as needs when a justification is needed.
