A better analogy might be cigarettes or psychedelics. I believe mountains of evidence strongly suggest cigs are worse for us and cause a much worse net negative harm on society via increased long-term strain on our healthcare sector. But, just like planes, people hold onto cigarettes as a right to freedom and attach unwarranted stigma on psychedelics (just like some attach unwarranted stigma on using trains). Banning cigs in some circumstances where the other is allowed makes sense if we just think about overall human welfare, insofar as that is our goal. Same goes for planes.
