I'm also not concerned with or pretending that alternative modes of transport are full replacements of cars; basic comparison of the modes obviates that.
I also don't own a car, and if I did I wouldn't consider it precious, or be worried about anybody taking it away. Public mass transit advocates always go there though, it's a pretty common ad-hominem-adjacent implication. Cars are just generally a better experience. They go from A to B, and they don't have other people on them. Those factors make them obviously desirable.
If somebody comes up with a teleporter I can install at home I'll use that instead. Maybe then I'd consider that precious, or even be in love with it. It would save me a lot of time.
All of that aside my main point is to push back against the idea that more trains solve any problems with US transit, especially looking forward even a little into the future. They're complicated and time consuming to build out additional infrastructure for compared to an airport, and solve a transit gap between self-driving vehicles and air travel that will likely increasingly narrow.
