I don't think banning all advertising is a good idea, there is some of it which is actually honest and useful.
A good 95%+ of them are a cancer upon society and even our planet though. I find it insane that we are told to behave as responsible consumers while there is a multibillion dollar industry which sole purpose is to change consumer's behavior.
Yes, 100%. Advertising is nothing but an unproductive arms race for who can deliver the biggest assault on your mind and your attention. Your life would be better, and all your products cheaper too.
