We can also see why the abstractness of intellectual property is not the crucial factor. Other forms of abstract property represent shares of something. Copying any kind of share is intrinsically a zero-sum activity; the person who copies benefits only by taking wealth away from everyone else. Copying a dollar bill in a color copier is effectively equivalent to shaving a small fraction off of every other dollar and adding these fractions together to make one dollar. Naturally, we consider this wrong.
