Having all of those blocks would be fine, but it still requires you to move the trains through at a certain interval. What it comes down to then is how fast you can get trains in and out of the stations.
A good example would be to imagine that Millennium Force had a mid-course block. As it stands now, their dispatch interval is about a minute. At the end of that minute a train is arriving and a train is leaving.
Now add a mid-course block, cutting the course (time-wise) in half. That means you need to get a train out every 30 seconds. I don't know about you, but I think it's obvious that guests couldn't get in that fast.
You might then argue that an additional brake area could be added just before the stations. That might be true, but it means you would just have a loaded train sitting there, so capacity is not increased.
Get it?
