I've critiqued this "value is complex" [http://lesswrong.com/lw/y3/value_is_fragile/] material before. To summarise from my objections there:

The utility function of Deep Blue has 8,000 parts - and contained a lot of information. Throw all that information away, and all you really need to reconstruct Deep Blue is the knowledge that it's aim is to win games of chess. The exact details of the information in the original utility function are not recovered - but the eventual functional outcome would be much the same - a powerful chess computer.

The supposed complexity is actually a bunch of implementation details that can be effectively recreated from the goal - if that should prove to be necessary.

It is not precious information that must be preserved. If anything, attempts to preserve the 8,000 parts of Deep Blue's utility function while improving it would actually have a crippling negative effect on its future development. For example, the "look 9 moves ahead" heuristic is a feature when the program is weak, but a serious bug when it grows stronger.

Similarly with complexity of human values: those are a bunch of implementation details to deal with the problem of limited resources - not some kind of representation of the real target.
