There is no way to avoid the necessity of making a value decision. Even if one chooses the "will of god", they still are making an arbitrary choice. (Never mind at this stage in history the vast smorgasbord of "divine wills" to choose from...).
It all comes down to human valuation. Create your own or follow someone else's. Inevitably.
Hm, I can't disprove what you are saying outside of my own experience but I'm also not sure you can prove that all value decisions are arbitrary.
Aside from the fact that such conclusion (which I assume is based on logic/rationalism - but you can pretty much sub any other scientific/philosophical concept here) itself appears to be as constructed (aka. arbitrary) as any other value system, I also think that while arbitrariness may be a logical conclusion when viewing experience/existence/etc. in abstraction, I would argue that at the very least, experience/consciousness gives humans some evidence/reason to believe that value decisions are not or may not be arbitrary, and I consider our direct experience/consciousness to be a very significant data set to consider in spite of how non-rigorous it might be. Put another way, through observation I have concluded that while many people do say all value systems are arbitrary, I have yet to see one person who I would say lives their life as if that were actually true - even my most sociopathic friends (dead writers or real people I know haha) appear to have a strong preference for self-preservation or rationalism.
I'm mostly interested in the concept of self-preservation, aka. the assumed value in continuing one's existence in the first place - I would argue that almost everyone I know makes decisions assuming that their life has value, and that such value decision does not feel arbitrary at all even if logically it seems that way - I think this conflict drives a lot of very smart people crazy or at least annoys them, and to me the existence of this conflict is not insignificant.
As I've said before, I started paying attention when was I 14 and I'm 29 now, so my 15 year data set trends strongly as described =) Of course yours or any other persons experience of consciousness may differ greatly, that's the crazy part about it all I guess.
