I am arguing it's not not inherently positive or negative, but you can become someone that views it as a negative or a positive. Many people enjoy walking as a time for reflection and to de-stress. Other types of repetitive motion like folding clothing can fill the same void.

However a big part of this is simply how much space your keeping up. An efficiency can be kept clean though habitat, a 1,000 acre estate takes a staff.

PS: That's not to say having groceries delivered is a bad idea, just maximum productivity is simply a wasteful goal.
