This blog articulates some of the reasons well. Many people claim the "ritual" of brewing coffee correctly is calming or grounding or something. I myself realized that the rigamarole was born of a sort of neurotic desire to live up to a stupid social expectation to have the correct tastes. In fact, I like the taste of cheap coffee - thin, vaguely burnt... yum (due to nostalgia? Maybe, who cares). In fact, I often dislike the lighter roast and terroir and whatever of "good" coffee - my wife and I often joke that it tastes like vegetable soup. I take my coffee with cream anyway, which I imagine blows out the subtle tasting notes anyway. It's how I like it!
Saving money is great. Though I'm still very much afflicted by the nagging worry that the cheap stuff, not being organic, shade-grown, fair trade, etc. is brought to me by African slaves toiling in a cloud of nasty herbicides. I hope not though!
