That is like saying "Hey I know you really love playing Tennis. That you enjoy the game, and how you feel when you play, and after the match. But we are going to outlaw Tennis, why don't you just go play Basketball instead? Mmmkay?"
Yeah sports aren't transportation infrastructure, and most forms of transportation infrastructure are perfectly useful to let people "clear their heads." This goes for walking as well as it does sitting on a bus or train. Just because the way the world is now put you in a habit of doing a thing doesn't mean the world needs to stand still so you can never have to change.
This is like saying "Riding horses is one of the few ways I can clear my head." Sure, if you really love it go to a paddock. But that's not what we're building our cities around anymore because "clearing your head" isn't really what we design people's commutes around.
