It's a freedom you agree to give up in exchange for a st of freedoms that many commercial operators would give much for. A radio amateur has great ability to muck other people's systems up if not careful enough. In exchange for the ability to do all sorts of risky (to others rights) arcane things without any checking or oversight etc you give them the ability to tell who you are asap so they cam come knocking if you stray too far unawares. A good protection. Honoured more by formal observation than strict compliance. eg some modes are not clear or decipherable without a priori knowledge of them. With such the operator may sen and ID in 'clear' every say 30 minutes or so or whatever the requirement is. Or not. In quite a few countries CB radio is banned and in others the power restrictions are ludicrous. Radio amateurs are given immense freedom and power. The men in the black helicopters do not NEED your address to find you, it just puts makes them in a better mood when they arrive :-).
