Such as the 10'000€ minimum assets that were required for an Ltd. in Germany until a few years ago. (The problem was basically: How do you handle a company going bankrupt? The legislators said that any company should always have enough assets to cover its liabilities. Obviously not compatible with the snowball-scheme based startup scene).
This is indeed an obstacle to creating a company, but there are quite a few more, all having to do with just plain ol' bureaucracy (handling monthly tax reporting, interacting with the tax authorities, handling insurance, etc.) The previous issue of The Economist made a case that these bureaucratic problems are even bigger in Italy.
I've recently been kicking around the idea that it's kind of weird that some hard-hit places in the EU like Spain or Greece sport up to 50% unemployed young folks (18-35) - these people are highly educated, just out of college, eager to build/work and yet they are economically inactive. My theory is that this is because it's hard to set up any sort of business activity due to the bureaucracy. It's also socially discouraged because it's risky.
If you're in something like software and have no immediate plans for employees or large investments you can get the bureaucracy done in 30 min. It's literally a one-page form with address, name, purpose.
That is a significantly higher cost of entry when compared with an Ltd/LLC, not to mention a sole proprietorship.
I went this way after consulting some other folks in Berlin and a tax consultant that I found myself. I'm kind of surprised that there's a different, easier way to go. Thanks for sharing the information.
