You're being obtuse. It's simply a case of a tragedy of the commons, the commons in this case being available real-estate. Paris is already one of the densest cities in the world, if you add more tourist lodgings you have to push somebody else out. Besides you make it sound like enabling more tourism is unambiguously a good thing. It's true that it has positive side-effects (mostly on the economy) but it also leads to degradation, overcrowding and, as we were discussing, an explosion of the cost of life for the locals. I often hear tourists complaining that they don't get an "authentic" experience abroad, how could they when the place they visit have been deserted by the locals?
