I never said no innovation would happen with out regulation that absolutely is not true. But cant you admit that the regulation on stoves have greatly improved the function of our stoves? And the same for our cars. I am sure some innovation would have happened without that regulation but it would have been much slower and less complete.If you are making the discussion that innovation does not happen without regulation, you would have a tough time proving that. Competition above all drives innovation and improvements. 50 years of materials science and engineering is not from regulation. People want cleaner and safer cars.
