Actually, that law is very well suited to the french mindset.
(Witness the recent protests at the watered-down pension "reform" the government passed today.)
Do *not* expect any consumer revolt; the french *like* protecting their local businesses from anything vaguely resembling competition.
Of course, they also squeal with outrage any time they see comparable products selling for significantly less in comoetitive markets.
I believe France is the point of origin of the phrase: "Eating your cake and having it, too."
