I'm generally for the idea of staying active, to promote healing with prescribed movement and 30 hours/week of physicsl activity isn't unheard of in my life -

but I'm not sure "always" is the right answer ... always.

I do agree that a lack of physical exercise can cause its own type of pain that counterintuitively can be relieved with movement, or the best thing after a long run is a brisk jog the next day, but if I severly sprain an ankle, maybe it's best to just rest that ankle for a while.
