Because the point of resoure management is pacing.Not trying to be contrary, but I'm just not understanding how the game session time has anything to do with resource management in-game. Real world time does not (necessarily) correspond to in-game time in any set ratio. Players track their resources on their character sheets and then recharge as appropriate when a short or long rest opportunity comes along. A day in the game takes as long as it needs to take, whether the PCs engage in no combats or 10 combats. That could be 1 session or 6 sessions or there could even be several in-game days during a single session. Not sure how 6 sessions in real life being one day in-game is a strain on the game. Can you say more about that? Is there a concern that players will get upset if their PCs can't use (or at least have available) all their abilities every session? Sorry, I'm probably missing something here - it's just never been an issue at any of our tables in the last 5+ years.
The only thing I can think of is some are playing West Marches style, where it really makes sense to have the in-game action end with a long rest at the conclusion of the session as all PCs are back at "home base" so any possible combination of players and PCs can participate next session.
And the most natural form of pacing is per game session.
If you have a big button that says "Be awesome", then you want to press it. If you never get to press it, it loses its lustre.
You have to balance awesomeness vs frequency. That, at the heart of it, is where the balance point really is.
