I agree that an update to 802.11 would be nice, unauthenticated management frames are a potentially nasty issue; but the rest of the argument is nuts.
All sorts of crimes can be committed by means of a speech act(indeed, many crimes are hard to commit without some means of communicating, fraud, extortion, ransoming hostages, etc.); but that doesn't give them constitutional protection, any more than the argument that your god demands blood sacrifice would provide protection against murder charges.
This is classic Locke stuff: a restriction aimed at restraining speech is illegitimate and illegal; but that does not imply that the mere use of speech to commit a given act necessarily covers that act under the protections given to speech. Same with religions. Restrictions targeted at a given exercise of religion are unacceptable; but this does not protect someone who breaks a law established for suitable unrelated reasons.
There's also the (only partially related) matter that 'radio interference' need not always imply "really loud white noise or other stochastic garbage at the appropriate frequency". That's often the easiest way, and for relatively primitive radio systems that have very few features to exploit it may be the best one; but if RF emissions specifically tailored to cause a radio system to fail aren't 'radio interference', what exactly is? Higher level attacks offer substantial advantages in power requirements, precision targeting, resistance to noise-mitigation mechanisms, and so on; but just because they aren't pure noise doesn't make them not interference.
