Ventures are an easy way to make supplemental gil while doing other things. I hate mining for shards, but with the level my retainer's at I can have her get 60 shards in 40 or 50 min, I forget which, and that's more than enough to keep me in stock since I don't craft constantly. My DoW retainer does the Quick Venure gamble, but I've also had him get snurble tufts and such when I saw the market was right for selling them. Some Quick Venture things are instant discards, but I got a Tonberry chandelier which I sold for several hundred thousand gil. It's not hard to make gil, and what's considered 'a lot' is a matter of perspective.

I have a small house and am satisfied with that, but I know plenty of players with med and large houses and not one of them is selfish or greedy, or buys gil. The way I see it, players who have a net worth of 50 mil gil + earned it doing things I chose not to do, that's not unfair at all it's a matter of choice.
