The US is far less dense than China. China’s population is heavily concentrated on the eastern half of the country. The US has pockets of high density, spread all over the country, hundreds or thousands of miles apart. Major hubs include the Northeast, the Atlanta area, the Chicago area, the Texas triangle, Denver metro, Phoenix metro, SoCal, Bay Area, coastal Northwest, Miami.. building a HSR train network spanning the whole system would be massively expensive, and the density of the US makes it really hard to justify.
