That's not really a very good argument. If you change parameters in a complex system then the odds are that you are going to find pathologies in new places.

People claim seatbelts have caused lots of deaths, and I'm sure at least a percentage of these claims are fair ([0]). I still think it's safer to drive a car with a seatbelt rather than without.
