There is more to it than just the direct cost of the concrete. In most cities single family neighborhood sidewalks are "owned" by the property owner, not the city. However they are an "easement" which means the property owner has no control over the property, or ability to limit access to the property but assumes all costs in maintaining, and all liabilities for injury or other city ordinances (like snow removal, grass cutting, etc) basically all the downsides of ownership with none of the upside. for some people this makes sidewalk undesirable
