In which case, Austin's line of reasoning is correct.

If you wanted to do an analysis around the CG (one of those things you could do "just for fun"), you'd need to account for friction on both legs. As you're working with floor level as a pivot point, neither leg's friction has any effect--except to help generate a moment, which for this particular problem is negligible (PVC on carpet not having a very high coefficient of friction).
