If ads were merely about being informative, they would be boring. But ads want to manipulate, so they have to be flashy and appeal to your emotions.
They pollute your mental headspace, and have no place in a healthy society.
Let's ban billboards. And then let's follow that up with a general purpose ban on paid advertisement.
Essentially, to get the word out about your organization or product (whether for-profit or non-profit), you'd have to convince someone with an audience to feature you *without paying them to do it*. In other words, your organization or product or service has to be genuinely interesting on its own.
And, since nobody else is allowed to pay for people's attention, you aren't competing with budgets, you are competing with other ideas. Imho this makes for a much more interesting information landscape.
If advertising is blocked, the exact same amount of dollars will be spent perverting every public speech.
