no, that's not the conclusion. I didn't bring up the "let's have a license requirement for cyclists idea." My point is that this is not a change that would improve cycling in a way that outweighs the negative effects. It's a bullshit idea that gets floated from time to time.

Improve cycling by all means, but use something that is effective: better infrastructure, education, enforcement. The Berlin police introduced a police squad on cycles a few years ago in one district and that has proven to be a very effective method: For one, they enforce road rules for people on bicyclist, but the major effect is that they remove cars from infrastructure dedicated to bicycles which in turn actually enables cyclists to use that infrastructure and makes people less likely to ride on the sidewalk, for example.
