I agree with Dino on this.

We need to find ways to lead and not follow, even if the technology and 
the consequences are not to our taste. The market will do what makes 
economic sense even if it is not "pure". Pursuit of purity in the face 
of economics leads to irrelevance.

This seems a useful body of work to complement our traditional 
approaches to this problem.
