In Sweden this is already basically banned, it’s nearly impossible to get a permit to setup a billboard anywhere because it has to be approved by municipal and land owner. It’s so difficult that i know a guy that bought many chunks of land and put up a 100M high baloon advertising instead because it doesn’t cover land and is exempt. It would have worked if he didn’t make the ads so distracting that it caused an accident and he was forced to stop by order law.
