That's not the right argument. The right argument is if there is a problem with something not reflected in the price of the product a reasonable approach is to tax the product to cover the externality and thnm STFU. The externality in this case is emissions so tax the emissions and STFU. There is no good argument for government to treat one emission differently than another, it matters not whether said emission comes from a kardashian private jet or public transit carrying nurses and doctors to provide charity healthcare. Tax the emission and STFU. The STFU part is very important because free markets are self regulating, which lets people making good capital allocations prosper and limits bad allocators and most of you are bad allocators, especially most of you government types and authoritarian types. Let the market run and be pleasantly surprised by the unforseen benefits that accrue to you. (Government should still aggressively break up monopoly and oligopoly but that is a different discussion of a corner case rather than this discussion of the core tenet of how the system functions so well.)
