My opinion, HSR is not value for money due to the followings:-

Due to its high construction cost, the fares will be very high. And when there are existing cheaper alternatives, most people would resort for cheaper alternatives unless for something more urgent. The train will not be frequented by normal passengers but for the rich. It might be full during festive season but not the normal days. So in the end, HSR is only good for urgent business dealings, richer travellers and festive season. When alternative options allow you to arrive at your destination the same day, the faster HSR is not so attractive. Dont forget one needs to first travel to HSR station first. and for the trains with multiple stops, its going to take longer time.
