I mean, it's understandable that you don't want to be mailing banknotes to Google Play to get your copy of Despacito, but you can definitely buy credit with Google Play in cash (at least in Canada and the U.S.).

Yes. In Indonesia, for example, less than 3% of the population have credit cards, yet online shopping is extremely popular, with many payment options (reverse ATM, as you describe, or paying at one of the ubiquitous Indomaret or Circle K convenience stores, and so on).
Steam actaully offers 'cash on delivery' for games through their Indian payment partner. The payment provider will send someone to your house who will collect the cash payment and log it in their dashboard, which will trigger it being activated for download in your library.

These Americans need a dictionary for everything, and that's why we love them. Imagine if the British imperial loss over in USA, was a British intelligence job. Owning you for decades you poor Americans.
