The poster is the author of the website. So I think it's self-promo mixed with "hey, look how interesting is the amount of 'bureaucracy' involved when one wants to move out of Germany"
I don't gain anything from promoting my free, hyperlocal content here, but I love to talk about my work and the discussion here is unfailingly interesting.
I liked it, even though I have no intention of changing my domicile from Germany.
The checklist somehow seems very German, including the advice that you don't have to turn in a resignation letter if you're fired. I know that sounds snarky, but the bureaucracy laid out is so vast it's actually warranted.
As a USAmerican though, I see it as more general—a statement about how modern, "1st-world" civilization has become so god-damned complicated.
I catch myself (especially since I have kids) realizing how difficult it is to navigate some aspect of modern life (for example, various payment methods—credit cards). A kind of mantra that always rises in my thoughts is, "No one would ever have designed the system to work like this."
Somehow, independent actors, independent reasons, likely the ability to make it this complex has indeed made it this complex.
It's no surprise then that just functioning in this modern society induces a level of background anxiety. Pretty much the opposite of "touching grass".
I don't live in the US, yet US centric news are covered here on the regular. Hold your horses and don't interact with a post if you are not interested.
