You guys are missing the point that once a time traveler goes into the past and changes stuff, it doesn't matter if HIS future changes. His actions still had consequences in THIS timeline.
When Lt. Yar went back on the Enterprise-C in "Yesterday's Enterprise," her future where there was a Klingon-Federation war never happened. But she STILL EXISTED in this timeline, and her daughter continued to exist.
Likewise, Daniels and FutureGuy and the Sphere Builders and the Borg interacted in the past of various "Enterprise" episodes, and those episodes are STILL a part of history in this post-Nero timeline.
Like Lt. Yar in "Yesterday's Enterprise," Daniels and FutureGuy may have come from futures that no longer exist in the future of THIS timeline, but their existence in the past is still a historical fact. The Xindi attack and Suliban incursions and the Broken Bow incident are all still historical facts that Commander Spock can look up in the Starfleet historical records.
In "Voyager's" "Endgame," Admiral Janeway came from a different future that will no longer exist in the "Prime" timeline, but the crew still remembers what she did, and the consequences of her actions are still a part of history. Daniels and FutureGuy and the Borg Queen are no different. Even if their futures cease to be relavant (or even possible) in this new timeline, their appearances on "Enterprise" have still happened.
