RP means ROLE PLAY, everybody wants money in RL, Freelancer might be in the future, but people still want to have money. So it is part of the ROLE you PLAY that you want money. There is no better way to RP then create a realistic environment. It is much easier to work for money then to work and say you do it for money, but actually don't get any, you would need to act like you do, but it's much easier to act like you really would in a situation. As such we need that situation and the situation requires money.
