Because no one uses gold or enchanting mats in this game?I guess we'll break this down.
Are there a numerous amount of posts from people complaining about the state of loot? Yes. But we can also deep dive into those posts and the content discussion being had. If the popular opinion sided vastly in your favor, which is what you claim, the threads would all be circle jerks of people bitching about the state of loot. Alas, that is not what happens. What usually results in these type of threads is a diverse range of specific opinions, ranging from "get fucked casual" to "gimme enough loot to hit max ilvl by week 3 of a tier release" in spectrum of content, with the closer you are to either end of the spectrum the less you're willing to actually have a discussion and would prefer to just live in an echo chamber of your own bias.
The vast majority of people side with neither extreme and really fall into some realm of "x loot style isn't perfect, but I prefer it over y at least" and some will even discuss how they would improve upon the current situation.
You can have an opinion an opinion such as "I prefer less loot that means more over an overabundance of loot that mostly went to waste" without it meaning you think the current system is perfect. Like I said, and you ignored earlier, I think the current system can be improved upon. The thing is you're currently running on the "I refuse to see the merit in any opinion but my own" group right now and you immediate dismiss/deny anything that does not confirm your bias and instead of bringing any actual useful discussion to the table you result to attacks on people who disagree with you and dismiss it with the statement "I can't understand x people who do y." That's entirely on you for not having the capacity to engage in a meaningful debate of opinions.
I am not "bending over backwards" to defend Blizzard's game design like you seem to think I am. I provide feedback where I choose to. Sometimes it's positive, sometimes it's negative, but I always try to provide it in a way that is constructive, which is something you apparently can't understand since you're so quick to dismiss any content of what I've actually said.
