And if you did want to write it in close to one line, it wouldn't be particularly difficult either.

Simply outlaw _selling_ (or giving away) of ad space in public.

You want to put your own logo on your storefront, side of vehicle, brochure, public bus, charging station? Sure. You want to sell that space to the highest bidder to place their own ad? Nope.

This would eliminate 99% of billboards, bus stop ads, etc without creating any ambiguity as to whether a business is allowed to identify itself in public.

One caveat might be that it would be desirable to carve out an allowance for e.g. "10% of sales go to Charity X".

Good news! I now am a landlord whose sole property for lease is land upon which a sign can be placed. I also offer an unrelated sign building service and my friend offers a sign painting service!

That's great. Now you can advertise your sign building service on your property.

If we assume advertising is ROI positive, wouldn't this quickly become a world where only the biggest companies could advertise? Apple has a large retail footprint and could buy the physical billboard footprint; my local tax accountant cannot.
