Sorry, but that's nonsense. There's already legal basis to suppress various forms of computer codes today. Think of malware for example. "Hacking" is considered a crime in the majority of jurisdictions. Moreover governments tend to be very creative when it comes to prohibitions. If there is no legal basis, then it will be quickly designed...

Besides that, even modern fiat money can be considered a virtual good, because the biggest amount of it only exists in electronic form. Various states have already recognized Bitcoin as a form of money.
