Why do you think you should not reproduce someone else's web page -- in whole or in part -- without written permission?

It is wrong to reproduce someone Else's web page without permission because it is basically plagiarism and that's wrong. Plagiarism is wrong because it means that other who worked hard, diligently and actually thought out their assignments are being robbed by other students who copy/paste and may get a better grade since its from a professional standpoint. Also, people deserve money for all of their research, you cannot just lift it directly, you are allowed to make reference and take ideas however, but a direct lift is just theft.
