> There's nothing inherently immoral about rationing healthcare.

That a subjective statement, it is only true for you and those who agree with you.

>In fact healthcare is already rationed everywhere for most patients.

That is not an argument for the morality of rationed healthcare.

We could make some sort of objective argument based upon ethics though. Suppose the smoker became addicted to cigarettes as a by-protect of being drafted into the military where he served in a distinguished role perhaps saving lives and protecting your freedom. Being a draftee and not particularly well educated, this persons means in retirement were quite limited, often depending on government assistance in various forms.

A different person was ensured to be wealthy by inheritance then draft dodging then engaging in tax evasion, illegal migrant labor, various kinds of fraud and strong arm tactics. Yet this person didn't smoke and is quite wealthy.

Should we invest in healthcare for tobacco users?

Everything is rationed, because the Earth has finite resources. Healthcare is no different. Morality has nothing to do with it.
