Insecure against what?

If encryption is done right, MitM gets the attacker nothing that can't
be done equally well with an RF jammer.

Yes, using RF is vulnerable to jamming (and other things which end up
being functionally equivalent to jamming).  It also makes traffic
analysis attacks easier.  Without breaking the crypto, that's all the
attacker gets, though.  (Of course, if the crypto is done wrong, it may
be easy to break, but it's not fair to blame that on the medium it's
carried over.)
