@esther I probably hate advertising as it is more than most people, but we have the old saying: "even the best wine needs a banner", and I can't dispute that.

Example: It recently crossed my mind that maybe I could rent cargo bikes when needed and turns out I could! This service would've been very useful to me, but I simply didn't know about it before. An ad in this case would've been beneficial for everyone.

My point is that ads don't necessarily "inject" a need but an option. Problem is that while the latter increases buyer freedom, the former increases seller revenue so guess which type of ads we see more frequently...
