Expanding upon this, GURPS, unlike some other systems, allows you to create characters that don't make sense. This is a consequence of being able to build anything at all. Its awesome, but it means you do need to pay attention to what you're doing and make sure you're not leaving something out. Wealth and skills are but one example.

I could totally see wealth as an optional rule. In fact, in a game all about gaining wealth (perhaps DF or traveler), I might just use a points for cash system and drop wealth.
