Buying gold in wow

Can wow please offer gold for purchase. You can buy a character level up which is like 16 days of time for my druid, 5 days at 60. Why Cant the wow servers generate gold and basic mats onto the AH to avoid all the demand supply inflation, If wow both generates gold and puts say peacebloom and linen on the AH it should be ok. I don’t know all the mathematics for a good economy. I want my Yak and 230 gear. I already purchase and farmed 100,000 gold worth of heirloom maps. Nothing seems to be selling well anymore. I’m tempted to buy gold from overgear. Is this safe for your account? I heard in a voice that they hack wow servers to generate gold and hack player accounts too.
