Edit:
I think the simple equation is correct, and that all the local friction points integrated simplify to the simple equation because up and down friction components cancel and the faster velocity areas also have proportionately lower pressure.
But if this is true, then a wing would have the same skin friction as a perfectly flat board of the same plan form.
