[Riesling]

I think this is an irrational fear. I don't think that leeching lies in human nature. People naturally want to take part in society as long as they are healthy. Just think about what you would do if you wouldn't have to work. Would you stay in bed all day? I would most certainly write programs to help other people, just as I do now.

Have you ever run any kind of business where you are giving away something for free? People will eventually take more and more until you go out of business.

"I don't think that leeching lies in human nature"

I think many thousands of years of human history proves this statement false. Leeching is one of the core components of human nature. Businesses (or governments) that take this into account will be successful. The ones that don't will fail miserably.
