Let's say a stack of ore costs 20 gold.
You farm 20 ore. You now have 20 gold worth of ore. You spend this to level JC. You've just spent 20 gold worth of ore to level your JC, ore which you could have sold in the AH and made 20 gold.
You buy 20 ore. You spend this to level your JC. You've just spent 20 gold worth of ore to level your JC, 20 gold which you could have saved if you never bought the ore in the first place.
Either way, 20 gold spent.
Whether you farm the ore or buy it makes no difference. You always end up spending the same valued amount of materials. If you don't happen to have mining on any of your characters, then instead of spending time mining for that 20 ore you can spend time making the 20 gold some other way.
People seem to have this misconception that if they farm materials themselves, then the end product is free. It's never free. The materials always have value.
