You can say the same for solar panels and/or batteries? After all, they exist right now and can be mass produced. Moreover the electricity grid actually accounts for a significant chunk of global emissions, unlike aviation. The only thing really stopping them is cost, but then that's basically the same issue that HSR has, which is cost/delays/political issues.
>As I said, we were doing this stuff in the 19th century, and have kept doing it (in some countries, just not NA).
"[trains] in the 19th century" aren't a serious competitor to airplanes in the same way that ocean liners aren't a serious competitor to airplanes.
