Your text is overly emotional instead of being what I asked for. Its about numbers. The positive things have a value X, the negatives (that so long no one has to pay för) also, lets call it Y.
If X > Y so be it, but limit the Profit at |X-Y|. Its not anyones decision what X and Y are, but facts that can be empiricaly derived. I dont care how many uses substance Z has, I only care about Y not being dispersed without liability, which happens today. If Y is too high, the Market shall regulate itself and will provide alternatives.
