Well, it'd stop the vandalism and town theft, the originally defined issue: Free publicity that leads to sign posts being stolen. For a tiny village of 100 people, this is likely a serious hardship.

But more notably, it's a way of moving the problem into a more concretely defined space, ideally out of sight and out of mind (and the money is just a bonus). Such a shop would become like the tourist portion of any large city -- a place locals avoid, and captures most of the visting rabble.

You'll still have your vandals and troublemakers on the street, but hopefully at significantly reduced rates.
