Legal, regulated, taxed?

Today, for a change of pace, I've decided I'm going to try to think of a list of things that I think can be questioned on moral grounds, or on the grounds of their social cost, but should be legal - since making them illegal causes more problems - but carefully regulated, and that are worth taxing to recover the full social cost of the enterprise.

• Tobacco
• Meat
  
• Alcohol
• Driving
  
• Firearms
• Cosmetic surgery
  
• Hunting
• Sharp pointy things
• Marijuana
  
• Prostitution

This list is sorted by approximate increase in mortality caused by allowing them in the US, so far as I could tell. Prostitution is at the bottom, because as best as I could tell from the comparative statistics and studies, legalizing prostitution seems to actually reduce prostitution-related mortality. Curiously, it's the least lethal two at the bottom that are most often illegal in this country.
