I'm sure you mean well, or at least as well someone who wants to restructure society according to their current hobbyhorse can possibly mean. I like walkable urbanism myself. But the problem with this kind of argument is that people know there are countries where you can have huge highways without this kind of thing happening. Some of them remember living in, say, America circa 2014. And while we cannot--nor should we want to--go back to the benighted days of eight years ago, people will naturally wonder if it's not possible to revert those changes (whatever they are) that made this specific kind of problem start to happen, instead of just plunging ahead into the total revolution of their way of living.
