For example to make sure that a company can be held responsible when it breaks the law.
There are already enough loopholes to disconnect legal responsibility from profit-taking, and not every company is benign.
Sure, if the documents cannot be acquired in X days for other reasons, that would undermine the tagline.
But I don't think that's the main risk.
Let's not forget that some requirements make sense.
In Germany, the government recently decided that some minor applications to local governments must be answered within X days or else are automatically approved.
But "minor" is important here... great for a small business that applies for a permit to renovate there outdoor seatings or whatever.
I wouldn't want for company foundings to be auto-approved without submitting the legally required documents.
