> In many other cultures its considered strange to just walk around for no reason

Name a single one.

Walking being natural, as is meant colloquially, is not contingent on whether the environment has been altered. It's contingent on being out-in-the-world.

I was referring to a book I read by a Brit who lived in Africa for 30 years. He wrote about an interaction where he moved to an African village and "went for a walk" through the village. The locals thought he was strange to walk for no reason and assumed he was looking for workers.
