i believe so , because the chakra he would have been using to control the one tails is now available to him and the sand still protects him, but he is also intelligent , calm minded in almost every situation and more so i think yes
Gaara is a F'ing MONSTER without the Beast. Why do I say this?
The moment the entire world found out his sand mastery came from his MOTHER and not the 1-Tails, I have never doubted him again.
He has all of the same talents except the raw chakra power of a tailed beast. But he is still Gaara of the Sand regardless of that tailed beast. The tailed beast gave him power but he lost consciousness after a certain point (b/c he was not a perfect Jinchurriki like Bee and Naruto) so I actually see the 1-Tails as a hinderance instead of the source of his main power. Think about it.
Lets not forget... He's also probably going to use his fathers Gold Dust Sand technique going forward. Oh yea, I forgot he BEAT HIS FATHER without the one tails or gold dust. Beasty!
