i'm not entirely sure what the author intended, but what i took from the article is that there should be a general consensus that some sort of physical separation between cars and pedestrians is necessary to protect pedestrians from cars, and failing to build that protection means you're failing to protect pedestrians.
it's up to each individual jurisdiction to decide how much they want to protect pedestrians, but when a pedestrian is killed by a car it should be acknowledged that a bollard probably could have prevented that, and not doing the thing that would have protected a pedestrian was a decision that was made for reasons such as "it's expensive" or "it's ugly". The people or organizations making decisions to not protect pedestrians should be held liable for choosing to endanger pedestrians.
too often, the response to a car running into a person or building is to either claim nothing can be done about it, or to blame the driver. no protections from cars is seen as a road designer following best practices, and they've done their job acceptably well. and that should be corrected.
