You sound like you're deeply entrenched in bicyclist activism or something, but I'll try to elaborate on my view any way: Keeping bicyclists off the road hurts no one. There are cars, public transit, Uber/Lyft, sidewalks+crosswalks, etc. No one is entitled to be able to ride a bike on the road in the same way that no one is entitled to be able to transport themselves via jetpack. If it can't be orchestrated in a way that deters misbehavior, then it's not a workable construct.
