Factually untrue, Nagato tried it on KCM Naruto.
Who is physically inferior, as Nagato restrained him easily with one hand.
Kaguya and Sasule both can easily do so.
They never attempted it in character, so they wont even try.
You're referring to Naruto resisting it, but he had specific training with battle for control of Kurama's chakra in his mindscape. Nothing remotely implied the same would apply to Saitama, who's never even encountered such a technique.
Doesn't really matter, both he and Oro resisted the ability using physical force. This is irrelevant anyway, as they wont get the chance to use such techniques, which require the target to be held in place for a significant amount of time. Saitama will likely one shot Naruto and Sasuke after their first attack.
He can be made into a gravity core, just breaking the rocks coming to him isn't a counter to something like that.
A single punch will be enough to destroy the rocks, the rubble and the surrounding vicinity, Saitama has also shown resistance to gravity manipulation so the attack will probably not effect him.
