TPTB will have hard time defining and / or defeating crypto-currencies.
The legislation defines them as personal use assets, so crypto transactions are akin to barter arrangements. For the tax purposes, virtual currency is treated as property for U.S. Federal Tax Purposes.” In Germany, Bitcoin (and other cryptos) is "private money" which can be used in "multilateral clearing circles.”
Nick Szabo used Chaumian protocol to coin a "digital bearer certificate" term, incorporating digital cash and distributed capabilities (secure distributed object references). It was in 1997.

Yeah, the the language can get pretty damn sophisticated but if page after page of definitions and sub-definitions are used to box scenarios in until they can be considered infallible there's still the issue of enforcement. Just as you say with Libya, tptb can go to extreme lengths to get their way, will they go as far as creating a scenario to justify crippling global communications? I honestly don't know but it's not inconceivable and that honestly scares me as it's hard to come up with a peaceful scenario for that and what do a few million lives matter when the stakes are power?
But that's getting a bit ahead of the point, laws are only relevant where they can be applied and the law knows its limitations and knows that trying to extend its reach too far can bring its legitimacy into question. Trying to enforce authority on something like crypto is extremely risky, if its something people want then even the very best case scenario is heavily tarnished with fascism and as crypto is ever evolving it's far more likely to end in humiliation.
There was once a little company that thought they could take on open source in the courtroom called SCO. Well, not such a little company actually, quite a big company, back in their hayday they probably had somewhere around the same kind of market and share as Oracle has now. They tried to claim rights to Linux but couldn't win that battle and they had Microsofts might behind them, it wiped them out.
