I could never be a communist since I do not believe in a "common good". However, depending on your religious beliefs, you might not want to toss it out so quickly. The early Christians were communists. Acts 4:34-35 says:
"Neither was there any among them that lacked, for as many as were possessors of lands or houses sold them, and brought the prices of the things that were sold. And laid them down at the apostles' feet and distribution was made unto every man according as he had need."
Note that this was an entirely voluntary form of communism; not the state enforced Marxism that is generally meant by the word "communism" today. Still, I could not live this way, since I view the fruits of your labors as yours alone to do with as you wish. If, however, you choose to put it in a common account, to be used "for the greater good", that is your business and not mine.
