There are two points:

1. Instance owners aren’t ready to be a community manager and moderator. Also, a big instance costs much more. Many people just want to pay their 5$ in month and passively make their contribution.
2. Not all users are “power users”. They want to consume content. To make federation successful, we should provide a smooth UX. Balancers, meta-account, something like this. Smart enough to require only one click and utilize all available resources.

Yeah, this is exactly my point. But I suppose a lot of people think that starting new instance is enough. But, unfortunately, it isn’t.
