Who is talking about punishing hydrogen? And what about the fact that gas is currently massively subsidised, is removing subsidy a "punishment"? And what about the fact that we all need this air to breathe and we're all collectively subsidising this lifestyle with our health? Also note that trucks bringing goods into a city could still be subsidised separately from other things if we chose, and that bulk goods distribution have more options for on-premises fuel tanks than people's homes do, things don't have to be binary.
