Its so badly and obviously misguided as a technique to that intent that it is simply implausible that that is the actual intent, specifically in that it does the exact opposite, and that it is transparently obvious that it would do so, and that even if you might excuse someone for failing to recognize this in a vacuum, the fact that a number of similar previous bans have been both proposed and implemented in Europe, and France specifically, with wide media coverage and the same counterproductive effect makes it impossible to believe any policy maker anywhere in France (or, on Earth for that matter) could, other than through willful ignorance, be unaware of the likely effect.
