The US is huge. If you were take a 300mph (nearing 500kph) train (which would make it the fastest train in the world), it would be OVER an 8 hour trip from New York to LA. (Again, about 2500 miles or 4000k)
Even in some of the densest areas, the trip times end up being pretty long due to distances: dc to New York? 600 kilometers or almost 400 miles.
The proper point of comparison here is more medium length trips. There's no reason not to have a high speed train for Portland - Seattle - Vancouver, for example.
Sprawling, low density, single use zoning, combined with parking minimums, have much more to do with it.

Most people ARE interested in coast to coast travel. It is called flyover country for a reason.
There are a few exceptions like the Baltimore corridor, or the San Francisco peninsula, and these are in fact serviced by good trains.
It is always shocking to me when I land at an airport in the US and there no public transport available.
It is common for conversations about good local public transport to have a retort in some sub-thread about how big the US is, as if the feasibility of long distance travel affected the feasibility of other modes of local travel.
You mention the SF peninsula. When I first moved there, I lived in the westside of SF and had friends living in Sunnyvale. On a weekend, it took 4 hs to get to Mountain View (~40miles, at the time, checking now it seems like Caltrain weekend service might have improved, so the same trip would take about 2hs), and then had to be picked up by car to finish the rest of the trip. It was faster (~3:30hs, if more expensive) to go from Paris to Amsterdam (>300miles) by train.
Let's take a hypothetical scenario:
- 5 hours flight time (average for NY and LA), 2 hours on each side to get to and from the airport to the actual city. Total is 9 hours.
- 10 hours train time and 1 hour on each end (which is generous given the proximity of train stations to city centers), 12 hours.
The difference is not that much, and a train ride is so much less faff than a flight that it's not even funny. Little to no security theater, you don't get fondled by security agents, you don't have to stand hours in line with silly passport controls and luggage checkins/pickups. And the list goes on.
A good train infrastructure can be vastly more pleasant than a good air infrastructure. Where air wins out is intercontinental flights where trains are truly not an option anymore.
You're losing an entire day on the train. You still have to deal with luggage pains, now you're eating on the transportation which will be inferior, and will have similar problems with last mile transportation.
Flying is currently not a great 8 hour experience, but it beats losing an entire day. I can do LA to NY for a weekend trip. (I personally wouldn't but there are some that would for sure)
Trains can and do make sense even in the US, and we do ourselves great harm by underinvesting in them, but there will always be a place for plane travel.
We're building a fast train from Toronto to Quebec city in Canada. It's going to be a lot more comfortable and way faster than driving. A MP in my family takes the train from Montreal to Ottawa very frequently, they don't want to bother with parking in the capital and they can work on the train.
I've ridden the Wolverine, it isn't half bad.
I 100% agree trains might be underfunded in the US. The LA to NY flight will stay preferred to a hypothetical high speed train due to time. It is unlikely ever to be less than 10 hours.
For train rides under 4 hours, and if you can get trains running smoothly (less stops), the time spent on the train and the overall integration of trains is a lot better as a mode of transportation.
