i think this is a bad read, people buy stuff because it's easier than pirating. pirating involves going into shady sites with porn ads and viruses and all that crap. it involves installing scary exes and cracks and whatnot. you have to go get your console hacked and lose your warranty. buying a pirated game has you looking through folders of games wondering if they thing you just bought will even work and if the guy that sold it to you when it doesn't is gonna be there when you ask for a change
etc.
buying your game legal (generally) saves you that hassle. that's the benefit vs the cost of some/more money.
if the person you're trying to sell a game to is not interested in that you're never gonna get that person's money. if the person you're trying to sell a game to is interested in that but can't afford it, just sell your games cheaper. there's regional pricing for a reason and in the digital store age there's no shipping costs for people to worry about
that doomsday scenario you're thinking of, there's no reason for things to get to that unless ppl start failing to deliver on that (like arkham city on pc, terrible regional pricing like in australia, making the game progressively worse like mgs5, attaching terrible drm, etc.) and if that's the case it's clearly that you just didn't hold your part of the benefit vs cost equation
not really
i bought arkham city for a friend on steam not long ago cos my friend didn't even know how to buy a game. my friend's a smart person, a lawyer, etc. etc.
and ppl don't want to play the free version with annoying ads, cmon
