Communism, good or bad?

You say that government isn't needed for communism to work, but communism IS a form of government. Who would uphold the laws, the military, the taxes? And socialism is not the same as communism, In socialism, those who have a drive to succeed still accomplish that. But in a truly communist society, resources are applied by need. Have you ever read a book called "atlas shrugged"? In that novel, one of the main themes is that those who need are not trying hard enough. I dont neccesarily agree with that, but the point is clear.
