DIY cable elevators

I know that there is opinion on both sides of the aisle as to whether elevating speaker cable is a worthwhile or pointless thing to do, or a good or a bad thing sonically.

Assuming for the moment that it might be desirable, can anyone tell me why the following DIY solution would not work as well as, or better than, the expensive products out there that The Cable Company is trying to sell me?

Take three chopsticks or similar lengths of narrow gauge dowel, align the three of them, tie a piece of string tightly around them about 2" from one end, splay the three legs out like a tripod, set on floor, and rest the cable in the "cradle" formed by the three short angled lengths of stick above the string. Repeat as necessary. Last I heard, wood is pretty non-conductive. But perhaps I'm missing something.

(Of course, if this works, we can start experimenting with different woods and different shapes and brands of chopstick.) (;
