As for whether an incremental approach or a completely new HSR ROW is warranted, I would say it depends on the the situation. In places like North Carolina, I would say incremental is the better approach. In Calfornia however, this is definitely not the case. The single biggest problem is that there is no reasonably fast train service between the bay area and LA. Due to geographical and infrastructure constrains an incremental improvement on service isn't going to work here -- you still have the trains meandering up to Martinez from Oakland (it doesn't even serve San Francisco) then when you get to Bakersfield, the line stops and you have to switch to a bus the rest of the way to LA because the Tehachapi Loop is filled to capacity. All told, it's 8hr30min between Oakland and LA. That's compared to 6hr15min driving and 1hr15min flying. Even with incremental upgrades, you would hardly approach the driving time and you couldn't even touch the flying time even when you take into account the whole airport routine (getting there, checking in, security, etc). CAHSR is only going to take 2hr40min between SF and A (maybe 3hours-ish if you're one of the cynics). Despite this, the San Joaquins are insanely popular which means the time to build true HSR in California is now. There's only so much infrastructure upgrades can do for a line, and in California's case, that isn't enough.
Your point is well taken, but we have to note here that the overwhelming majority of travel in a slowly-developed "California Supercorridor" would not be from end-point to end-point. It would involve at least one of the intermediate stops, and might well involve a local-transit feeder within one of the Super-Metro "anchors".
While the recent emergence of $4/gal liquid fuel might have put the brakes on the trend for the time being, the history of urbanization in Californis is such that "horizontal", rather than "vertical" construction has predominated, so much so that places like Lancaster, Victorville, Gilroy and Santa Rosa are now "exurbs". Travel from and between these points. even when use of a Corridor rail system is only a modest part of the overal journey, both strengthens the contribution to the overhead and demonstrates the potential benefit if the system overall is improved, and travel times and congestion are reduced, albeit marginally.
Admittedly, this is a very long-term process which none of us here will see to full fruition ..... but the underlying economic and societal factors continue to inveigh in the right direction.
