Doctors don’t get to bill for idle time. Being less than fully utilized is leaving money on the table. The idea here is presumably to compensate them for leaving gaps in their schedules.
What you're describing is effectively what doctors did: they left their entire calendar free until the last moment and only took appointments then.
It turns out this is not actually what people want; people want this availability to exist, but also do not want to be turned away if they book ahead of time, which points to this being a capacity problem, not a scheduling problem.
