The notion that there's anything inherently wrong with walking is really bizarre.
It is also bizarre to make a claim about "better run" countries where people just walk home instead of other transport methods
Edit: You seem to be having a conversation with yourself and making points that no one is arguing with. Maybe try replying to what people say instead of forming a different argument and then attacking that.
Of course there are plenty of American communities that I'd describe as highly walkable, but even then you have social matters to contend with, such as rampant "stranger danger" paranoia and lawsuit culture that, in America, have some school district in walkable communities forbidding students to walk to school for liability/paranoia reasons. I don't think it's bizarre to describe communities without those two issues as 'better.'
