So consciousness has meaning because it solves problems which enable consciousness to exist?
As for arguing that it brings order, I think you'd find it brings at least as much chaos as well. Besides which, order is just a term you force on something. There is to be, nothing else - chaos or order doesn't matter.
Yeah. Good or bad, enabling matter to have Volition enables it to become an Agent Of Intentional Change, repurposing matter for new ends (tool making, recording experiences in pen and ink and language) that it wouldn't have developed naturally, and generally transcending the physical cause-effect relationships that govern the unconscious parts of the universe (the stuff that shapes geology, stellar fusion, and whatever else is out there).
The only reason Meaning exists at all is because consciousness can ascribe meaning to changes, or cause-effect relationships. At a fundamental level, Consciousness creates meaning. It's an intrinsic property of awareness and volition.
Conciousness doesn't have meaning per se, but it means I can experience things and I like experiencing things. Like food. And video games. And so much bloody anime, holy shit.
Anime and the ability to appreciate it is totally also a reason that consciousness is valuable. Enjoyment aside, language and culture created by conscious things for intentional ends creates stuff like Anime, which (however silly or profound it may seem) lets ideas exist and convey things to people, like enjoyment or hypothetical scenarios or whatever. More forms of rising complexity, where inert stuff like DVDs or monitors displaying animation is made to have Meaning it didn't have before.
I'd recommend this short essay, for exploring some of the value of consciousness and language and all that. A bit anthropocentric, but the idea is there.
