Reason 1: Original mp3s, films and other stuffs are too expensive to afford for many people. Moreover, access these stuffs from the Internet is easier than find originals from the Internet or place of sale.
Reason 2: Celebrities can make profit from live performances. They can give concerts or gain money from box-office receipts.
Reason Against: Free downloading must be illegal because famous people can' t gain money.
Refutation of Opponent' s Argument: If free downloading is illegal, celebrities make a loss instead of make a profit. Because people will think their stuffs are too expensive and they won' t buy them, neither can download them.
