. Space under the curve is more important than either peak torque, peak hp, or peak revs, which is why the Renesis will be an extremely satisfying engine despite having a low amount of torque because, unlike other high revving, low displacement engines, it puts out a good amount of power throughout its powerband. I can't wait til Mazda dealers get them so I can take one for a test drive....

I'm not one of the types of people who believes that torque is everything and that high powered, low torque cars are slow as it may seem from reading my first few posts, and I'm sorry that I gave that impression.
This part of your post I completely agree with. But, unfortunately, most of the cars that we drive are street cars, not all out race cars, and their designers have to take things like fuel efficiency and engine longevity into consideration.
I just get a laugh out of these things because the vast majority of people think that the torque numbers on your dyno graph is actually whats there at the wheels.

This also means that, at 75 mph, the engine would be spinning at 5000 rpm, not only causing a considerable drop in fuel efficiency but also greatly increasing wear and tear on an engine that is not going to be rebuilt after every time it is used, as F1 engines are.

You of course realize that you are quoting rpm and speed figures that are very close to real-world for the S2k.
