While I get your point this is really unnecessary when you fly within Europe. Specifically within the Schengen area. Usually you don't hand your boarding pass to anybody. Instead you self-scan it once when you enter the passenger / transit area and a second time, when boarding the plane through a self-service gate. This may vary by airport, but on most of my flights through a number of European airports access is pretty much automated.
