It's not an argument, it's marketing to non-techies. Put it simply you have to sell more phones than you did last year (selling less, or even the same amount, isn't enough). If you don't have features to justify that (which you don't, as the very fast smartphone evolution has mostly stagnated), you make them up. 5G being one of them.
