> Having to share your phone number does not meaningfully affect security and privacy.

Of course it does, way more than "meaningfully". I actually wonder if I got your message right taken that I am not a native speaker of English.

Do you mean that if your phone is public (and you are known to be the owner) you will not get creepy calls, have ot listed as a free pizza delivery for calls after 23:00, having it blacklisted, ....

I must have understood wrong.

Otherwise what is the number of your president/prime minister? Or the CEO of Google/Apple/... I do not think they are public.
