Because I can, it's my money, I earn it so therefore I can do as I wish with it. It's people like myself and many others that do spend that keep little companies like Kano running so very little spenders, like yourself, have a game to play, without people that do spend, games like these can't progress to the fullest potential. Think of it like social security, only the spending players are social security and people like yourself are the recipients.
