Faulty logic on the soda tax

Evidently, according to  this op-ed by Dick Armey in today's USA Today, Congress projects revenue from a soda tax to increase every year. 

If that's the case, then why are its supporters saying that taxes on soda (or beer or wine or whatever) will help us lead "healthier lifestyles."  They count on people drinking more so they can get more taxes, but sell it as an issue of health. They can't have it both ways.
