When the government is run by criminals, and the corporations are run by criminals, and the law enforcement are criminal, you think the rest of us should play by the rules?
Assuming you're in America, it's impossible to outright ban ads.
You can make whatever laws you want, but those laws can't supersede the Constitution. And the Constitution says that companies and people have the right to free speech. And that the government, I.e the laws you just created, can't infringe on that (with some reasonable exceptions).
At best you can make certain advertising types illegal. I lived in a wonderful town that banned roadway signs, for example. You could ban billboards over a certain height. You could regulate the color palette used for signs on shops. You could say no signs posted on roadside easements.
So progress could be made, but not an outright ban.
