There's absolutely no evidence that we wouldn't have gotten to where we are without brutal male-led dominance hierarchies centered in subjugation, discrimination, and Might Makes Right. How many more inventions and scientific breakthroughs would we have had from Black people in America and from women (as just a few examples) if they had been respected and allowed to be a part of mainstream society? What you are putting forth is rhetoric you've heard that is essentially patriarchy trying to justify itself, but it's hogwash.
The world was well civilized before patriarchy ever came along 5 or 6k years ago.
We had agriculture, medicine, writing, boats, huge cities (run essentially by neighborhood councils), beer, weaving, complex religions, trade, etc, etc. - much of that invented by women, in fact.
As already noted, competitiveness as it's described in relation to harmful Man Box norms doesn't mean no competition - it means sensible competition where every other man is not your rival for some sort of imaginary position in an artificial hierarchy.
Stoicism (which means emotional repression) and aggression speak for themselves about why they are harmful. What exactly is so dreadful about pointing that out? And those three traits all weave together to create dominance hierarchy dynamics. You can't show emotion because that's vulnerable, and you can't afford to show any soft spot to anyone because they are all your potential rivals, so men end up desperately lonely and isolated - which is well documented to lead to depression, substance abuse, suicide, and a host of other physical symptoms as well - such as poor sleep and high blood pressure. Because you have to literally fight for your place in the Man Box hierarchy, violence against other men as well as women and children is baked into the system.
Denmark isn't a Utopia. They still have a lot of vestiges of patriarchy from just a few decades ago, but they also teach empathy in schools, cooperation, competing primarily against your own past performance (although obviously there are sports teams and other types of healthy competition), and other sorts of pro-social values that are considered not just nicer, but also key to being a good manager or leader and Denmark has one of the strongest economies in the world, particularly given it's size.
The only thing that's foolish is to ignore the ways that patriarchal Man Box norms are very literally killing men and making them miserable. A lot of the most profitable companies are the ones who are moving away from old dominance hierarchy metrics and traditional "male" ways of doing things. There is zero evidence that we need to treat each other that way in order to have progress, and all the evidence in the world that it's driving violence, an epidemic of loneliness, rape culture, and all sorts of other dysfunction.
Research has shown that firms with more women in senior positions are more profitable, more socially responsible, and provide safer, higher-quality customer experiences — among many other benefits. These aren't "alternative" ideas - they are extremely mainstream, well-documented, and understood by anybody who is bothering to actually look and notice - rather than to just keep soaking up the BS rhetoric that the upper echelons of the dominance hierarchy use to keep men buying into a system that harms them. You've drunk their Kool-aid. You don't have to keep drinking it.
Average men don’t count for much in a patriarchal dominance hierarchy, and the way to distract them from that fact is by giving them nominal control of and status over women. But as that aspect has eroded over the past 50 years, the focus has turned instead to blaming women for all the ways that late-stage capitalism and the elites have disadvantaged the average man.
Unfortunately, this red herring has worked rather well in some quarters.
