Every ad you see materially makes you a little bit poorer and cuts off a small amount of your life. Think of it this way - every ad is a few seconds lost, maybe a few minutes, and a few cents down the drain.
But this isn't understood because it's so abstracted. The link between your personal shopping habits and advertising is not understood, and, in fact, cannot be understood, because it's fundamentally brain hacking.
If you believe you are immune to ads, you are not. Or, at least, you can never prove it.
Cumulatively, this adds up. If you never saw ads, how much longer would you live? A year, maybe two? If you never saw ads, how much richer would you be? 200%, 500%? Who knows.
Also, the lifespan thing is crazy - what if you learned about something that improved your health, like an exercise machine or something? You can't just ignore the upsides. What if you bought something that saved you money in the long run, like a quality tool?
