Your proposals are a bit contradictory. If you heavily tax something, it becomes a money source for the government; does it then make sense to try to extinguish said activity through artificial social aversion? Also, whatever is vilified by the government, but stays legal or at least feasible, will act as a magnet for the counterculture.

If you really hate something, just propose an outright ban. It would work for Porsches; no one can secretly grow a Porsche in his backyard.
