I'm making a different argument. We may not like ads, but all sorts of real things happen in the world in order to make ads, and as a consequence of ads. The ad industry is not on a trajectory to turn every last grain of sand into an ad-making machine.

I also made a prediction: It will be banned eventually. Not because I or anyone else doesn't like it, but because it is a disaster in the making. PoW currencies are already a significant drag factor on, for example, ML research. The drag factor is increasing, and it will be felt in more and more industries.

You can only replace so much real economic activity by literal hot air production before it causes an acute crisis.
