Indeed, I'm just noting factors in favor of building a demonstration line even if it might seem wasteful on the surface.
Shanghai-Beijing wouldn't be a demonstration line, it'd be an enormous project.
The Shanghai Pudong line was a demo and frankly it failed to sell maglev as a concept, mainly because of NIMBY limitations admittedly, that's the problem I think.
It would have to be a big project because you don't really get the benefits otherwise. The train needs time to accelerate and decelerate, and it's only worth building a track over a very long distance where it can mostly go in a straight line at top speed.
