Stuff isn't really all that illiquid. Ebay and its ilk have created a reasonably efficient market for random junk. There's still a lot of overhead, though: writing the ad, monitoring the auction, and packing and shipping the item is time-consuming. No matter how good I got at it, it would probably still take $20 worth of my time. But if you're poor, it might still be worthwhile.
