This is an interesting anecdote, which I can relate in a tangential way. I'm a huge fan of MMOs, and part of that fun is grinding for more wealth. Some of the games I played over the years at some point became infested with Real Money Trade (tl;dr people would buy and sell in-game currency with real life money), and over time such activities would make me quit the game because it framed everything in real money. Sure, I could play the game for 5 hours like I did before and make $5 USD in in-game currency, or I could do some freelance work and make 200x that.
