What is the point of gold? Once you have epic flying, and cold weather flying, there really isn't anything to buy anymore. While you might find epic gems to be expensive, how much easier could they make it to get them? You get blue quality gems from running H Oc that (1)you can transmute to epic gems, you get (2) badges that are pretty worthless besides buying gems (once you get your "free" T9). You get tons of (3) honor for doing WG and other BGs that can be used for epic gems. If you are really bored, you can watch hulu while (4) farming ore on your miner, and ask your JC guildie to prospect it for you. That is four different ways for you to get the gems yourself, without having to go through the AH. How much easier do you need it to be?
I have over 3x more gold than you do, and I havn't farmed this entire expansion. Gold really isn't hard to come by in WOTLK. In this expansion alone, I have given away over 100,000g. Seeing as how you don't need to farm your own food in raids (feast feasts only need to be dropped by one person), and you get two flasks per lotus in WOTLK compared to one in BC, raiding has never been less expensive. You can get the 2nd best Tier gear from running heroics, so gearing up hasn't been easier than it is now.
Not putting in the best enchants / gems in 232+ gear is just disrespectful to anyone you run with. If you excuse is you don't have the gold to buy epic gems, then you are lazy. If you have the gold but refuse to buy them, then you are selfish.
If I had the choice I would not bring you to my raid.
