Information can travel without people paying for it do so.

Ban most ads and everything will still work fine.

Sounds like ads will just get replaced with covert word of mouth enticements. Want to get people to know about your product? Send free samples to influencers. Maybe even fly them out to CES and put them in nice hotels so they can experience your product announcements/demos. All of this is "unpaid", of course.

I would prefer a world that returned to the older '30 second blip (for the only) sponsor of the program' ad, which also seemed to be of the limited form: Here's Product X, it does Y, which makes your life better because Z. Informative, dry, stated by an announcer in a calm and not demanding way.
