I think some kind of mix approach, example some countries ban some kind of advertising. Advertising medical prescription drugs and treatments is illegal in some countries.
Alternatively companies should pay me to watch their advertisements. Organize events to pay people to watch their advertisement.
With smart glasses AR and AI we should be able to block out all billboard, posters or it could go the opposite way glasses show all kind of adverts.. hmm. We need open source AR smart glasses with adblock.
