Reduce would mean you buy less. Reuse would mean you buy less or buy from other people. Only recycle means you buy the same amount as before. Guess which one companies prefer you do?
There's a form of broken window fallacy going on in green policy circles. Particularly the Cash for Clunkers program, and California's recent banning of trucks made before 2010. It is an attempt to drive demand and raw resource extraction to produce new equipment, by destroying existing supply of refined goods and driving up prices. Used cars are scarce now. Opposite of reduce/reuse.
*diesel Big Rigs/Buses. (It's an important distinction, as one would ban the majority of vehicles in the US). Diesel vehicles are particularly bad for the environment, and as we've seen even worse than we thought because of the widespread cheating from manufacturers for environmental testing, and big rigs & busses have previously had massive exceptions carved out for them from environmental regs already for a long time.
