You presume incorrectly, and as someone who doesn't know anything about photography, you sure are making a lot of assertions on how a camera should work. So lets get you straightened out.

This image also illustrates the biggest problem with histograms...you need to know where the tones of your scene should be, in order to know if your exposure is correct. but if you know where the tones should be, then you can expose them correctly without the histogram. That's why the histogram is useless.

If you just want to take pictures without having any photographic knowledge, then just buy a point-n-shoot. There's nothing wrong with that. But don't disparage Nikon just because they make cameras for photographers.
