Well it's tough (though not impossible) to build a any sort of value system on top of "I exist."

This is ludicrous. I have a value system. It consists of me feeling like a better person when I'm a better person. I feel no need to prove my value system as though it were a theorem - what an odd fetish. I've never understood this need.

Not sure why you need to build one.

Last time I checked, people tend to have one, irrelevant of the effort they put into building it. Is that one not enough? Why not? If you are missing one, why do you need to get one?
