Some thoughts...
Humans, in general, seek to improve their environment. One might paint their home, put out plant pots, tidy up, whatever else. In private spaces this all works out.
Advertising goes against all of that. It effectively states 'I can put this ugly thing here, and it'll increase my local happiness (because I don't have to see it), so screw the global happiness'.
I stated a similar form of this argument in another thread. There's a huge banner ad (larger than a person) close to my home, on a bus stop. The last I saw it was some sort of advert for supplements of dubious medical value.
My nice walk to the post office or whatever gets interrupted by this nonsense every time I go outside, big colourful unnatural full-face things reminding me that people are being duped into buying crap they don't need by other people that don't care about them.
I think, and hope, that one day we'll realise that many forms of advertising are effectively mental abuse.
