alt Hacker Newsthis agrees with my point because non-smoker are being counted in cancer risk. we're only interested in people who choose to smoke. public smoking bans make secondhand smoke less risky/relevant as a factor. we're only interested in the risk , independent of secondhand smoke, of someone choosing to smoke getting cancer.

No, that's where you're wrong.
You are only interested in that independent risk.
I, and many others, are interested in how much smoking changes that risk.
Picking random numbers, let's say smoking gives you a 10% chance of lung cancer. It's fine for you to only care about that 10% number, you get to care about what you want to.
But for the rest of us, when making informed decisions based on risk, it matters whether smoking changes it from 9.9% to 10%, or 0.1% to 10%.
