It's not right for my vices to pay for your infrastructure. Tax tobacco to fund cancer research. Tax alcohol to advance treatment of liver disease. Tax porn to fund, I dunno, therapy for people who can't view it in moderation.
On a similar note, I do NOT have a problem with paying for schools even though I don't have kids. It raises property values and that's a benefit to me and everyone in the district. Plus, educating young people benefits society as a whole. I'm not some "don't tax me" guy because taxes are good. They just should be limited and targeted and not levied unfairly against those with bad habits for the benefit / relief of all.
That said, I apologize for quitting drinking. Research into treating cirrhosis of the liver will have to take a moderate hit and that's my fault. /s but only sorta
