If your players care about the cost of grain in chiaroscuro vs the rising cost of papyrus in nexus and exactly how much those red jade eyebrow tweezers cost, then sure, go for it.  If not, I think you're wasting your time to adhere to a strick sense of accounting and not necessarily for anyone's benefit.
One of the things about exalted is that the money system isn't important, plain and simple.  Artifacts are handled separately and are not supposed to be handled via resources, so resources are there to cover either all the menial crap that you shouldn't bother getting in depth about and stuff so large that an arbitrary resource value is easier to handle than an arbitrary cost in jade since neither will really be dead on.  The money your character has is a background, it's not a focal point around which your character is based.  Compared to everything else that does take center stage, money doesn't need a complex system because who really cares about it?  It's a point of vanity for most characters, and if you have to count every obol you spend, then you're losing the benefit of having it in the first place.  You take resources so you don't have to worry about these things, not to give yourself more work to do.
Another problem comes down to the fact that resources really is, no matter how you look at it, an abstraction, once you reach a certain point.  In real life, you can look at how much you make on a yearly basis and determine what your equivalent resource rating would be, but it's difficult for all but the most obsessive to come up with a liquidated gross value of everything you own.  Resources isn't just what you have in your pockets, in your bank accounts or stashed away in a shoe box under your bed; it is your capability to continue generating income as well as everything of value that you own.
If your sense of reality demands such petty details be filled in, go ahead, but you really aren't adding anything to the game.  Abstraction, in this department, is a blessing, don't waste it.  The two pairs of socks and a belt analogy can be handled with fluff, since it really is fluff.  I don't disagree that you should have a realistic cost to each of these items, but that's not to say that you should bother wondering how much your character has left after such a transaction.
