But, imagine, self driving or not, having semi trucks line up and drive
over a railway spur. Then, lower their steel wheels, and drive off as a
train, of sorts.
This would get rid of the rail yards and all the messing around of
getting containers from ships to rail cars and later getting containers
onto trucks to deliver to their destinations. All of those steps would
be drastically condensed but you would still have, for the long haul
portion, the efficiency of a train.

Right. But we're talking about large trucks, not a train. Unless
drafting, each truck has to deal with wind resistance. But, with
drafting, your point makes the argument that rails would make a
significant difference.
Maybe the US should be financing a new kind of rail system or modify the
existing one. One where each freight car is self powered and can exit
the tracks and use rubber tires for "the last mile."
Yes. As an engineer, it is pretty easy to imagine a vehicle with both tires and steel
wheels, that can easily transition from one to the other "on the fly" while
driving at speed. It's especially solve-able with self-driving vehicles.
The challenge (as always) is that a good new solution is always crowded out by
a bad old solution that is already established. See quote below.
