I'm one of the rare remote in an office where most are full time there and I'm there one day a week.
I have no idea how they get anything done in there. I feel they only can focus before and after business hours.
So don't be so sure. Home has distraction when the mind is distracted. But once working I feel we are much more productive and capable due to long uninterrupted stints.
It does take discipline but that's what deadlines are for.
