It's all about cost benefit. There are just not that many people passing through Tokyo and those that do will probably want to make a stop (if they're in their right minds.) Building a spur to Shibuya or Shinjuku would make a lot more sense than trying to cater to some strange use case of people passing straight through Tokyo without making a stop.
Shinkansen stopping at your door? Well that's a combustible straw man if I ever saw one.
Where do you get this idea that people don't pass through Tokyo? Are you aware there are not a few people in Japan who don't think Tokyo is the cat's arse and would rather not be forced to stop there? Have you ever been outside of Tokyo? I have endured on the level of 250+ transfers at Tokyo station, of which around half were to/from the Shinkansen. There are always plenty of people using the Tokaido-Tohoku transfer gate.
I'll ask again - why is it necessary to force all those people to get off the train?
