Sidewalks can fit an order of magnitude more people than roads can fit cars. Especially if one car lane was re-allocated to make sidewalks wider. Less traffic means less air pollution.
It's almost never needed to faregate sidewalks. Tourist districts can organize a special improvement district tax on stores to fund sidewalk upgrades, trash collection, shuttles, security, parking, and planting flowers. This makes the zone more even more attractive to tourists.
This analogy pretty much gets at the heart of what makes these policies distasteful. Me walking or driving through my own city or neighborhood, where I live, pay taxes, and vote, is not the same as me taking a trip to Disney. I don't do it just for fun. I do it because living requires me to occasionally move from place to place.
Auctioning off to the highest bidder the right to move around is cruel because you make it so that some people simply can't afford to exist in public spaces, and because you're telling people that their own city or neighborhood doesn't even belong to them.
The correct analogy here would be access to healthcare, water, or electricity.
Are people entitled to drive through an area? Or are people entitled to travel through an area? When you live in a car dependent society the two seem to be the same. But they're not the same. Only 22% of Manhattan residents own a car!
Look at a school. Many make the front driveway bus only. Because parents dropping off kids one at a time was very low capacity and causing a line of cars to form every morning backing up into the road. There's just not enough space for everyone to drive single occupancy cars to the same destination within the same half hour time slot. Favoring school buses in the school driveway is not an attack on drivers. It's acknowledging the limits of geometry and time, and choosing to get the most out of our common space.
Does this imply that the government should buy everyone a car? Or is driving not actually necessary for existing in this space and it's enough to let people walk for free?
Keep in mind that we're not talking about some suburb where you have to drive two miles to get to the store, but rather about the most walkable place of its size in the US.
