Just imagine the radio interference that e.g. motherboards might cause if there were no rules limiting it. (As another, very practical, example of well-intentioned regulations, there is the 'CE' mark featured on products that should be safe to use. There is a test to determine if your product may carry it. OR - you can simply slap it on and wait to be challenged. Then, if the challenger proves you don't deserve the mark, you have to take it off. A procedure officially sanctioned as 'self-declaration'.)
