You don't want to end up banned from a movies forum because you also participate in a political forum. Federation solves that problem because you can use separate accounts without either forum knowing that you also use the other.

Honestly, it's strange to me how hard people are trying to make distributed anything happen. Federation mostly solves a problem that real people don't have or care about.
IMO, something federation is very good at is solving one slow-moving problem - enshittification of social platforms. It's not immune, of course, but an Elon Musk-style takeover is much harder with Mastodon than Twitter, and it would be hard to run it into the ground in other ways because the platforms are owned by different people and groups.
I would like to see a wikipedia-style system for Twitter/Reddit: open access data, non-profit.
