I think chaotic instances without a clear focus are superior in terms of a stable fediverse. If you have a 'main' instance for programming stuff, queer topics, German content etc. you're always at risk that the instance goes down and all content and communities die along.
Instances going down is a realistic scenario. Hacking / DDOS attacks, government takedown requests, copyright issues, hosting issues, admins losing interest... The more distributed certain topics are across instances, the more resilent they are against all these vectors.
I consider myself pretty left (at least in comparison to the average German), but that lifestyle sounds quite tempting to me. I'd skip chicken though.
