Because we unconsciously develop one hand better than the other starting in early childhood, so by the time we're teens and beyond we're habituated to using that hand for everything. Constant practice creates muscle memory.
If we would constantly practice with our "bad" hand, it would become more skillful, but that would be difficult, and it's so much easier just relying on what works, so we don't. People who lose a hand have no choice, so they do.
I think handedness has something to do with our dominant brain hemispheres, too. Right-brained people are more likely to use left hand and vice versa.

Most people who are ambidexterous (that is, use both hands well) are so because they were born left-handed and were forced to learn to be right-handed. Some people get lousy handwriting that way, and lack of dexterity. But some beat the system by using both hands well.
The one-handed wiring is probably an artifact from the time when survival favored those who could do things well with one hand. Then if they lost the use of the other, or if they had something to carry in the other, they were not too vulnerable. By knowing which hand was more dextrous (which means right in Latin, just to show how old the prejudice is), you knew where to put your sword and where your shield. Which would be passive and which aggressive. For women, which would wield the needle and which hold the fabric. Generally, you can do things better the more you specialize your brain functions, and so it has proved in terms of our evolution.
Now as to the debate as to which is superior, left-handed or right-handed, let me just say this: the right side of the brain controls the left hand, and the left side of the brain controls the right hand. So only left-handed people (such as myself, of course) are in their right minds.

Because of use. Watch small children. They don't have "handedness." It develops. Once there is even a slight preference, they continue to use the one that works better. As they use it, it gets better still so they use it more. It's what's known as a "positive feedback loop."

Imagine a race between a person who has been running all his life, and a person who has only run a race like twice. You'd imagine that the racer would be better, because he's been practicing, he's used to it, and he knows all the minute strategies. We use our one hand all the time, for all our lives pretty much, so of course it's better!

It is because we use the one hand more often and for more intricate things. If you were to practice for years with the opposite hand you would become much more adept.

Don't really know, which side of your brain do you use?
