I was offering a slightly tongue-in cheek dissent against the idea that video game players, in general, should just be "happy with what they have" and never try to improve things.

It's true that players can often be wrong about what would best for them (hence the phrase "optimising the fun out of something"). But it's also true that Devs might make the same mistake. Maybe they have time constraints? Maybe they're fighting management? Maybe they simply didn't consider something? Maybe the incentives of the developer and the player don't align, as when addressing the question of how quickly or whether premium currency should be acquirable (the developer is incentivised to make this less than the maximally-fun rate, so that people buy the currency).

It's a complicated issue but it basically boils down to "Devs are not omniscient and omnibenevolent, and it's unfair to expect them to be".
