PC Gaming may be mainstream now but in its nerdier days awareness of cracking was quite high... and I imagine it still is among demographics that cannot afford to plunk down $60 for the latest whatever-they-want
A lot of young people (or people in middle-income countries) can scrape together a few hundred bucks for an entry-level gaming PC, but would find a $60 game to be prohibitively expensive. IMO the move away from demo versions and physical media has substantially incentivised piracy - if you can't try before you buy and can't resell your game, you're less inclined to hand over your hard-earned cash for a game that you might hate.
You'd be surprised how many people with iPhones shoplift clothes worth much less than $60
When I was younger I could barely afford a gaming PC and certainly didn't have very much money for games, and I knew a lot of other people in my boat. I lived for the bargain bin (and later, Steam Sales) and it was still not enough
