Regulating Nanotech

I don't think we should be as steadfast in regulation as we should be in studying nanotechnology.  Here's a piece on local regulation at Boston.com:

Two dollar amounts are often cited in the discussion on nanotechnology safety risks. One is the projected value globally of all applications of this technology by 2015: $1 trillion. The other is the estimated $200 billion in   death benefits, medical care, cleanup costs, and legal fees associated with another miracle material, asbestos. If industry had invested more in investigating the health threat that asbestos fibers posed , thousands of lives and billions of dollars could have been saved.
