TL;DR: This is about offline communications and not the world in general. It also assumes that communication is achievable. In the real world (offline and online), we have problems with that. When you attempt to communicate online you are often redirected "through the gift shop" so you can be shown the exact number of ads such that you statistically won't give up and pick up the phone (and I'm sure phonecalls will have pre-roll ads at some point too). In fact, ad-hoc random person-to-person communications online are gatekept by "the algorithm" which would rather answer your question directly to keep you from meeting another warm body online.
