You said the USA was big. Now you're saying population is the important thing. Combined that's population density, so does Maryland have this? Connecticut? etc.

On the density front, NYC is famously high density, and yet so far as I can tell a monthly pass for just there is double the raised price this ticket will be next year: https://new.mta.info/document/118601

Most adults should be able to figure out that IN THIS CONTEXT "big" refers to land mass relative to population.

Yes, NYC has a dense population, and yes, it also has the best public transit in the country.

And your best is twice the price for something strictly worse. (I've used NY public transport, it's much worse than anything I've seen in Germany).

One thing adults often also do, and which you just did by continuing to ignore the point, is treat arguments as soldiers.
