Sasuke cant absorb senjutsu from the environment, so now that the sages mark is gone i wouldnt be suprised if sasuke had none left. Its not just gonna replenish itself when he doesnt have the ability to absorb any more.
Well you can't absorb Senjutsu from the environment, you absorb natural energy and combine it with your chakra to make a new chakra called Senjutsu which means Sage jutsu/techniques. It's true that he can't replenish it so when it's used up it's gone but I doubt he used it all yet since you would think the Sage would have a lot of chakra and he gave Sasuke his Yin chakra and Natuto his Yang.
I agree with you to some point.
You can get Senjustu but I'm trying to say Hagoromo sage chakra isn't equal to Senjustu.
Why not? Minato said he sensed hermit power Obito and Madara as Juubi Jin and Kakashi asked Madara how did he get the Rikudo's power. Sasuke told Naruto to use his hermit power then said he'll use his Sage power too when he made his black chidori. The Juubi is a mass of Natural energy that only SM Naruto could sense and the Rikudo got his chakra from his mom who got it from the Juubi. The Bijuus gather their chakra like they pull it out of nowhere and Yang Kurama does it by placing his hands together as Naruto has done to gather natural energy. Only Senjutsu or taijutsu can effect a Juubi Jin so does that not make Sasuke's Chidori fall under the same category? Minato sensed hermit power which Kakashi called Rikudo power so are they not the same or at least similar enough to be under the same category?
Sasuke can't make more and won't be given more by the Sage but he has the chakra until it runs out at least
