The most serious is ignoring the effects of sitting all day. Employers tout their big monitors and new laptops but I've never seen one advertise treadmill workstations.
Another rationalization is that longer work hours are somehow mutually beneficial but I find the opposite to be true.

Look again.
Anecdotally, I have actually seen them advertise this, and my company decided to get two. I see people using it all the time, but I have yet to see anyone do in depth work requiring interaction with the machine, mostly just reading and researching.
I was working at a treadmill workstation for 8 hours a day coding. Physically it felt great but eventually the number of hours concentrating on code wore me down. Now I work two hours a day on code and spend the rest of the day doing other activities. I was burned out coding at regular hours which makes me incredulous of those who claim productivity at 60+ hours a week.
