Even if all your assertions were true, it is irrelevant to the fact that we here in America, who claim to value our freedom, are prevented by our government from buying what we want with our own money. If the government wants to ban the use of these devices by government personal or at government owned facilities that's perfectly reasonable. Telling private citizens that they aren't allowed to take their own informed risks is authoritarian (which is ironic because that is the source of most of the legitimate criticism of China).
