Is there a serious argument being made that vaping is likely not bad for you?
As far as I am aware the main function of the lungs is to get oxygen from the air in to the bloodstream.
Using e cigarettes as a vehicle to get nicotine in to your bloodstream means you ask your lungs to manage not only the nicotine but also whatever other accompanying chemicals are in the vapour. Maybe you don’t have the tar that you get with cigarettes, but still get things like formaldehyde and heavy metals.
