Oh my god, that's literally the point of the whole comment. You are offering a perfect solution, while the only alternative you offer is a bad solution. EVs are not perfect. They are an okay solution that is better than remaining on ICE.
That was literally the point. Small towns with populations of <10,000 are not going to build rail in the next decade. I would love for them to, but they're not going to! So you're solution for them to get to town where groceries are is to... continue using ICE while sitting on their hands waiting for rail/bus service that is not coming? If that's your best solution then it's not a solution.
