Only maybe in US, more probably only in some weird micro bubble you live in. Otherwise all you write is false obscure projection. Maybe go outside more? Its pretty healthy also mentally
I also travel a lot and have visited many places where walking around is just not possible.
In contrary - people are way more outdoorsy than say 10 years ago, most folks are counting steps daily (I dont but I walk a lot regardless). Tourism exploded in european alps in non-winter times - i have a small apartment in a nice place and summer is cca on par with winter now, it was before covid much weaker season. Spring/autumn used to be empty times, not so much anymore.
Most folks we know or colleagues are 'outdoorsy' in some form these days, thats not some fringe group but majority.
Even countries like China have built lots of new car first infrastructure.
