If you did that, you would probably put half the operators out of business. Fences, security guards, lights, ID cards, it would cost a fortune.
Far better solution would be to simply secure the aircraft properly. A nice big chain from the tie-down to a ring in the ground attached to a large lump of concrete should do it.
Of course none of measures suggested on this thread would have prevented this incident.
More to the point, how many aircraft have been stolen over the years? (Apart from CGI?)
