So what? Airplanes also transport fewer people than a highway. How many people travel by air between LA and SF right now per hour? Probably no more than the capacity of Hyperloop.

>But the point is the same, regardless of if we use Japan, Germany, France, Spain, etc: 10k people per hour, or more, is easily possible.

What makes you think 10k people per hour actually want slow train service between LA and SF, when they can just use their car, get there in about the same time, and then not have to rent a car at their destination?

>And with the cost you could maintain teslas for rental on a dedicated highway for many decades.

You're placing passenger capacity above speed. The whole point of Hyperloop is speed: it's faster than an airplane, without all the downsides of the airplane (terrorism, TSA, crashing, etc.) HSR is not, it's slow (esp. the way they'll build it in this country). Of course, Hyperloop doesn't have the advantage of not having to rent a car like driving yourself does, but it makes up for it with very high speed.
