This is actually a very good point, most people here don't create communities they just go "oh well that community from Reddit doesn't exist" so it makes sense to create a community and hand it off to others since people who might otherwise want one aren't.

Honestly I think it's a good thing that someone is willing to take the first step and make these communities exist and hand them off to people who has the time and passion to moderate efficiently, because Lemmy does need content if it's going to succeed. Not just the popular "haha" communities but niche ones as well.
