A large part of the issue lies with the retailers who make no attempt to educate would-be drone pilots.
I suspect the problem would go away if retailers were required to pull out CASA's "Can I Fly There?" app when a customer was considering a purchase and show them exactly where they can fly their new toy. Once a potential drone-buyer sees just how restrictive the law is, particularly around those scenic areas in metro areas where they all want to fly and film, I think they'll put their $500-plus back in their wallet and use it for something else.
