That only works if you either don't care about retention or long-term gains(which is an extension of retention).
You can argue the humanist point of view to not burn people out or the business point of view that happy, well rested people produce better work over the long term. There's tons of data to back it up if you want to go that route as well.
I've found you can frame the productive discussion beyond hours in the office by emphasising that we work hard and use the time outside work to be refreshed enough to do it consistently month over month, year over year.
