I think insurance is the biggest concern. If you DO have an electrical fire your insurance company may decide that your defeating of the safety grounds means they don't need to pay you for your losses, whether or not your actions actually caused the fire.
Guess it all depends on your tolerance for risk. There are safe ground loop breaking circuits published using a low value resistor and a diode bridge that can solve noise problems without defeating the safety ground.
