The German Standards Setting Institute, a private organization which provides lots of standard template documents for startups, actually make it a focus to minimize the notary costs in many of their docs (and ironically, they have notaries helping them because some notaries also think it's ridiculous).
It is much simpler to set up a limited company in the UK, for comparison (which I've also done). And everything the author describes, about the IHK for example, and the Bundesanzeiger Verlag, appears completely stupid to me, too. What value exactly does the IHK provide me? I asked my tax consultant that, too, and he gave me a vague answer along the lines of "they do stuff for you and it's good", and I still have no clue what the IHK does for me.
The official letter for the Bundesanzeiger Verlag states "we know that you probably received a lot of fraudulent mail asking you to wire money to other bank accounts. Do not trust them, only trust this letter and send money to the following bank account." Really? Your word on your letter vs their word on theirs? WTF?!?
Yes, it is ridiculous.
