Everything has an upside and a downside. Eliminating all targeted ads will lead to entrepreneurship being restricted to the rich or the well-connected, which is not only unethical but anathema to me and many others.

I think the way forward is somewhere in the middle, targeted ads with restrictions and opt-outs. Polarization isn't a path to progress.

As an aside, prostitution doesn't have to be the crime magnet it is today (in medieval Europe the Church ran brothels!) And while most drugs are unambiguously bad, some are considered safe enough to be traded openly and very profitably - caffeine, alcohol, nicotine, and now marijuana.
