Thanks a lot for all these comments. My point in writing this article was not to discuss how best to regulate taxi services and how Uber should be accommodated, if at all. All I wanted to say is that very often in Europe, as opposed to the US, regulatory restrictions protect incumbents without even an indirect reference to the general interest objectives these restrictions are meant to achieve. As a result, any entry that is perceived to eliminate some rents is prohibited, completely stopping innovation in many sectors of the economy. Innovative entrepreneurs exist in Europe as well. Let them start an activity when entry does not immediately affect any general interest. Adapt regulation to new technologies instead of blocking any technological development.
