I grew up in a 16 hectare commie superblock - every common errand could be done via walking - that includes medical services. One thing I wish urban planners internalized is that you don't have to create an incredibly dense human pile-up to have walkability. It's actually worse like that because even if few people have cars, the vehicles will still be a nuisance. Also the 5% that is in the habit of littering will be that more of a problem. My neighbourhood consisted of buildings with an average total of 4 floors (including ground level) and a few higher ones dotted here and there with squares and playgrounds in between and this is what I consider an ideal population density.
