If any Hyuuga managed to block a chakra point in a tailed beast, not only would it smash their head into the ground, they would force their chakra into that point and easily unblock it.
In Naruto's fight against Neji, he was able to force some of Kurama's chakra into a point. This was through a seal, there were no tails and no cloak, just a tiny, tiny leak. That tiny leak was less than one of Shukaku's claws worth of chakra. Naruto now has full control over one half of Kurama (not to mention the other tailed beasts, if we talk about the manga). A sealing jutsu would be far easier, but still a very dangerous and difficult task.
