I don't think so, because there are too many things, but not enough time in life to find out your true preferences for them all, so we all are (to varying degree of) indifferent to most things, and focus on only a few things we truly care about. For you, it's coffee and rice; for others, it may be monitor latency and keyboard switches.
I'd used coffee as an analogy, because it's something that almost everyone drinks, has many varieties, but most generally aren't too picky about it. Alas, I'd underestimated the population overlap between HN readers and picky coffee drinkers. :-P
I'll agree people exhibit varying degrees of indifference to things. But where I exhibit clear preferences it seems to me it's because I took genuine issue with whatever I tried before that.
That said, someone out there is purchasing the $1k gold audio cables and similar items. So I'll acknowledge that not all people fit that description.
