One current big example are the new VAT rules in the EU for non-physical products. They just do the opposite, what a free market should be. There are already companies that say on their website, that they will sell to their own countries people and happily even to people outside of the EU, but not to people living in other EU countries. The total opposite what the EU once should be. The new VAT rules also should limit the possibilities of big companies like Amazon to circumvent VAT. In reality it become a big stumble block for smaller companies.
The EU is a big market, with many, many rules. To many rules and to few thoughts on the effects particularly for smaller companies. (instead, the big corporations are effectively writing the rules)
When smaller companies do not get the chance to come up (what is happening) than the chances for Unicorns are also greatly limited. Instead the same big players are winning again and again and are doing the same dinosaur stuff again and again.
