You're leaving out an important distinction. You don't have a right to do those things _in harmful ways_. If you are an unsafe driver (whether it's excessive speeding, drunk driving, etc) you absolutely should be barred from the roads.

I am actually very much a live and let live type person. Where I start having issues is when your lifestyle puts others in danger. Drink all you want... at home. Or in a bar. But get a taxi home. If you are going to be a belligerent drunk that's harassing others, you absolutely should be kicked out of even public transportation.

I am totally against MANY of the policies of the TSA (mostly on grounds of what's effective, and also what's unnecessarily invasive from a privacy standpoint). But I am not against the existence of something like a TSA.
