Its not imagination, you can quantify these things. There have been thousands of studies showing the economic damage of something like a polluting coal plant and its not like we pass these costs on to the polluter ever, so of course the price of a coal plant looks low when you ignore the hospital bills and the loss of biodiversity. I'm not going to do your book report for you though.

Please get back when you find any rational and serious quantification of these externalities, specially one which accounts for a few millennia worth of babysitting residues to validate a business that goes for a couple of decades.
