People agree with the Qun and look up toward it because they lack the mental capacity and the backbone to think for themselves, to understand the world and to self-actualize their place and role in it on their own terms.
People agree with the Qun and look up to it because they would rather be sheep than thinking individuals.
This would be true if the Qun were real in today's modern society. But it's not.
In Thedas, self actualization and backbone will typically just get you on the wrong side if a noble or someone higher up on the social ladder.
In the human and dwarven caste systems, it's never wise to try and buck the system. It took hundreds of years, countless wars, riots, and social political movements to move away from the system of nobility and courts.
In Thedas, the Qun represents an opportunity to be on equal footing with everyone around you and the ability to prove yourself based on the merits of your work, not your bloodline.
This is a ~really~ good deal to people not born above a certain level on society, and even to those born into privilege (the Viscount's son for example). When the choice is live in a mud hole and scrape out a living or live in a communal society where will always be fed, housed, an cared for, it's not hard to see why a commoner or an elf from an alienage would choose the Qun.
The mistake people are making is shoving their modern day thoughts and opinions into characters who would be spat on, laughed at, rebuked, or possibly beaten simply for holding those values.
This is a medieval world we're in. And in a medieval world, you're most likely to see people jump for the chance at a better life instead of scrounging through life and cow-towing to their noble 'betters'.
I should point out that I despise communism an socialism and any sort of collectivism you can name. Anything that wants the state to be in charge of your daily life beyond law enforcement an the maintaining of public roads and offices is always a bad idea.
