there isn’t enough content on Lemmy to only whitelist certain communities
This is really the central problem. There's way fewer posts on any given Lemmy/fediverse network compared to the major players, and I've been conditioned by the last 13 years I spent on reddit to have constant interactive stimuli and discussion based on my interests. That doesn't exist here because the communities are so small. Admittedly, yeah, I could post. But I've always been a commenter on existing discussions, not someone who wants to start the discussions myself.
