This logic doesn't follow. Most video games don't optimize their gameplay mechanics for conversion to micropayments - and the ones that do are widely under attack.
Sure, all mechanics in all games are man-made, but to continue the analogy, we're talking about an entirely artificial wait time to check out that's been specifically optimized to make you pay for the "express" checkout. In other words, the wait exists for no reason except to extract more money from you.
The whole core of the argument is that developers used to optimize the mechanics of the game for fun and enjoyment, and now instead optimize the mechanics for how frequently and continually they can suck money out of your pockets. There is now a gigantic philosophical and developmental gap between the "pay once" and "pay monthly" business models and the "pay always" business model.
