In so far as comparing levels of complexity, you're correct. But that's not the salient part of the the parent comment.

A tool with a vaguely defined goals and no stakeholders is easier to make than a tool that must meet certain goals as defined by stakeholders.

I'd disagree. Just like how no one needs to find an engine usable, no one needs to find a game fun. My personal itch.io account is full of games no one finds fun :)
