Instead of banning a particular avenue of advertising, which moves the advertising spend to somewhere else, why not have a broad-based tax on advertising spending? We've seen how ineffective things like banning advertising to children were on reducing smoking, while raising taxes on cigarettes was quite effective at reducing smoking levels. And some advertising is useful. I don't need no advertising in my life, I just need less of it. Taxes would reduce the "arm's race" effect where companies need to advertise because their competitors are advertising. I suspect that the quality of advertising would go up if it were more expensive, as well. Perhaps at some point in the future, we will have too little advertising and there will need to be a debate on how we should reduce the advertising tax. I long for this day.
