What's the good reason? In the UK I can started a Ltd with £1 of share capital, about £100 of fees, and filling out a form online. I will be shielded from personal liability if it goes tits up unless I've broken the law, knowingly traded insolvent, or otherwise been an idiot.
The wider thread appears to be Germans commenting that it's unthinkable that such a thing could exist, and thus it's all the author's fault.
