It's an important rule if you want the liability protections associated with a limited liability corporation
If you just want to start a business, without any associated shell companies or liability transfers, it costs $0 and requires filing one sheet of paper. It is very easy!

You're missing the point. There shouldn't be any capital requirement just to get liability protections. No one is forcing counterparties to accept liabilities.
clearly german regulators and/or voters disagree, as is their right
nevertheless it is very easy to start a business, and this man is complaining about an entirely separate problem (it is difficult to create and incorporate two shell companies)
