The good CFD software is also protected by the same regulations.
Plastic models just won't give anything beyond the rough shape, no information about the materials used, no information about the computer controlled dohickies that adjust the wing shape.
I suspect these companies have taken note of the merchandiing revenues achieved by film tie-ins (i.e StarWars) and are dreaming big $$$ (or at least enough to cover the lawyer bills for doing so).

Lawmakers always try to write (and represent) laws as black and white, they rarely succeed.
When they do, it almost always results in injustices like the one you used as an example.
