I've had to do Boston to NYC a lot lately. I wish it was faster but frankly not really sure how much value is added by going faster.
US cities are still fairly spread out so for someone to be able to feasibly commute on it they'd have to be a short distance (both their house and workplace) to the train station. My unsophisticated take is that it seems like better local transpo would have an easier time of finding enough people.
Obviously these aren't mutually exclusive, but the number of people that would take advantage of true HSR that wouldnt take advantage of slower rail seems small.
