This! When I lived in Munich, my dad visited and on one of our U-Bahn trips he mentioned how easy it is to travel without paying as there are no barriers anywhere. I replied that it is also ridiculously easy to actually pay for your trip, and the prices are fair was well. Yay for the honor system! It was a delight using public transport there, and every metro or tram stop had a working ticketing machine with multiple options, accepting both cash and cards. In contrast to many other places. Getting rid of the paper cards in Paris seems premature, if I read about the current alternatives, or lack thereof.
