> and have less emissions per passenger mile than high-speed trains

The optimal high speed train is about two orders of magnitude more efficient than the equivalent flight on a passenger mile basis. Might look a little different for crossing oceans or thin routes where it's really not worth building a thousand miles of rail to replace a flight a day, but lack of demand between nearby cities or is not why the US doesn't have any high speed rail network...
