If all the transactions being done wouldn't be forbidden by money transmission laws even if they were transmitting money normally, then the transactions aren't doing anything to negate the effects of the money transmission laws.
On the other hand, if a transaction would go against money transaction laws if it were going by some other method, even if it would currently be legal if done with bitcoin (which I doubt is the case, but even supposing), the money transmission laws could just be amended to also forbid the analogous transactions which use bitcoin instead of whatever other method, therefore then making it a crime.
A plan to invalidate a law by making a technology that fits through a loophole in a law, and hoping the loophole never gets patched, seems, an odd plan.
A plan to make a law practically un-enforceable by making a technology, seems like a more reasonable plan to me, and is also inherently facilitating a crime.
