I have had such days. I read a lot of stuff online, and I have adblockers. My entertainment is supplied by books and TV, where I watch either channels like Netflix or recorded shows, where I can skip through commercials. It's not exactly not encountering ads - and I surely encounter billboards when I drive around (though I don't think I can recall any of them, the mind filters them out by now), but it's pretty close and I'm sure I've had days where I didn't see ads. The thing is, they didn't feel much different from the days where I saw some.
> society, that overproduces things and where a large part of your survival depends on your skill to sell
That is preferable to the society which underproduces things and where large part of your survival depends on you skill in finding how to satisfy basic needs - food, shelter, etc. I'd rather watch ads than be hungry. My deepest hope is to always live in the former kind of society - where productivity is so high that it's ok to spend resources on convincing people to consume stuff. I've lived in another kind of society - where people spend resources on finding way to get decent food, clothes, books, etc. and where ads convincing people to consume some luxurious goods could not be taken but as a cruel joke. I'd much rather take the overproducing one.
