There's no point further arguing about this matter with someone who hasn't lived through both pre and post mobile phone eras.
I'll just add this, I was amongst the first to ever own a cellular mobile phone. I owned several Motorola 'bricks' (DynaTAC) if you're old enough to know what that is, and before that I owned a mobile car phone in pre-cellular times, the nature of that tech was such that very few phone numbers were available—simply it was damed expensive and one had to be very keen to own one.
What I'm taking about is a lot more complex than your understanding (or that which you wish to admit to).
