One, pedestrian congestion doesn't exhibit traffic congestion's negative externalities. (You have to get to trampling-risk densities before that occurs.)
Two, "sidewalk passes" have no precedent. Congestion pricing has lots of precedent [1].
Three, this is a problem getting attention [2]. America has spent decades throwing lanes at traffic. Not all of that was a waste. Similar effort has yet to broadly benefit pedestrians.

Also keep in mind pedestrians have to share space with sidewalk planters, outdoor seating, trash bags, and many times, cars parked partially on the sidewalk, making the usable walking space less than 10% of the size of the total street space, yet still allowing exponentially more people to move faster than the cars the street was designed for.
Why do cars need a 6 lane road through the middle of the busiest pedestrian neighborhood in the world?
