that is a silly argument. If you put up a billboard on someone else’s property without permission that would be illegal. If you drop a pamphlet on the ground in your own yard that is perfectly legal. In your perfect billboard free world, would you also ban signs outside of a business saying what is on sale? what about signs outside a private residence? What kinds of property would be allowed to display what kinds of sign? I could see telling government agencies they cant rent billboard space out on the side of the road, but if someone puts a billboard on their roof or the edge of their property I think it would be gross to stop them.
