You're thinking about this the wrong way.
Think of "Star Trek XI" as simply the latest episode of "Enterprise."
Instead of Daniels, or FutureGuy, or the Sphere Builders popping in from the future to stir up trouble for Archer and the Enterprise, it's Nero and Spock popping in from the future to stir up trouble.
It's one continuous timeline. Who's to say that Daniels, FutureGuy, and the Sphere Builders aren't all from the future (or futures) in which Vulcan was destroyed centuries earlier by Nero?
As someone else pointed out, once someone else changes the past, it stays changed, as we saw with Lt. Yar and her daughter, Sela. They went back to a new timeline, and the changes they made there were permanent.
Likewise, Picard and the Borg interfering with Cochrane's first warp flight before "Enterprise" still happened, even if they are from an alternate future, as Lt. Yar was, and Daniels and FutureGuy and all the rest were still interfering with the past on "Enterprise," even if Nero has subsequently erased their futures.
That simply means that Nero has won the Temporal Cold War.
There were plenty of "Enterprise" episodes where some time traveler said, "That's not how it happened in my past. Your timeline has been changed." That's exactly the same as what happened in this movie, which is chronologically, causally, and temporally simply the next episode of the "Enterprise" series.
