Given how much it costs to launch anything into space, and especially something big enough to be visible from earth, and the amount of sales gained vs. the massive expense, I don't think it even needs to be banned; the companies with enough budget to do it are already big enough to be known by almost everyone, and the small ones who would benefit the most from the reach can't afford it.
