Furthermore, the gate openings are taijutsu techniques, and those clearly require at least a flow of chakra. It stands to reason that if less chakra is flowing, that technique might be less effective. Something similar might apply to kage bunshins.
No, you're definitely confused about those 2 things. Taijitsu only uses stamina but i can be enhanced by using chakra by using techniques such as the 8 inner gates.

As for kage bunshin all i can tell you is that every time we see naruto's clones it doesn't matter if there are 10 or 1000 of them they always seem to demonstrate the same level of taijitsu but until we see some other characters using this technique i cant make any definitive conclusions about it .

Edit: It's probably forbidden since it's used for espionage and it's supposed to be a time of peace in the naruto world.
