Anarcho-capitalism -- er, "libertarianism" -- at its finest. It's a deeply nihilistic worldview.
Almost all these things are biologically addictive, and furthermore the companies selling them have long known about their addictive qualities and then built marketing campaigns to ensure the public was not aware of the risks.
Taxation is how you recognize the externalities of this behavior while maintaining a free-market system.
We’ve been taxing cigarettes at like 100% or something ridiculous for many years, yet just as many people die from tobacco-related cancers now (if not more) as did when cigarettes were much worse for you (no filters, more chemicals, etc.). Those taxes also did not help to alleviate any of the problems in the medical industry; or if they did, they were obviously offset by something else massive, since cancer healthcare expenditures have risen drastically since their inception.
Also, it’s easy to look at something like cigarettes which pretty much everybody would agree are a terrible idea, and say, “fine, tax em”, but what about when it’s sugar, then butter, then red meat, etc. Let people make their own choices instead, and just don’t put the onus on the rest of us to fix the problems of those choices. Banning smoking in public is acceptable because it’s no longer a choice that only affects yourself; it affects anyone near you in a really terrible way. But taxing cigarettes (or anything else) is no solution.
