Companies want to have it both ways and not have anyone notice what they're doing.
If you want butt-in-the-seat work, you're getting 40 hours from every employee and nothing when they get home. If things break, they get fixed the next morning.
If you want remote work, you're getting however much work is allocated per Scrum iteration. People will work weekends and evenings as they need.
If you want both, you're going to have people finishing their assigned iteration work and then fucking around for the rest of their butt-in-the-seat office time.
