Well. Flattr.com is based on a friend/popularity/credibility system. As is Kickstarter.com. But they're not really based on juridically defined rights, are they?

I'm not saying that Flattr.com, Kickstarter.com, Amazon.com etc are wrong. I'm saying that we probably need additional systems as well. Why make everything simple and uniform?

@NingúnOtro: Man-made tunnels are certainly a problem.
