I could go through each of your points in turn and disprove them but I don't think that would be terribly helpful. I think you're feeling merely the "vibe" of late-stage capitalism which feels very... gestalt. Greater than the sum of its parts. As if, even you go through and knock down every pillar supporting it by disproving every argument above, proving that its defeat is inevitable, it would still remain standing, seemingly uncaring about the fact that it should have collapsed. It's an almost religious force. I think finding ways to mentally contain and/or contend with that almost supernatural feeling of capitalism's permanence and "stay in objective reality" (so to speak) is something most people go through, though not that many are able to specifically name their malaise in that way due to a lack of political reading, and it instead comes out in a massive array of forms, sometimes liberatory, sometimes reactionary.

As all humans are not capable of perfectly logical thought, at least not for very long, we do have to live in our feelings and find coping mechanisms in order to keep functioning. Some go to stoicism as a coping mechanism, while others choose to ignore politics entirely and live as hedonically as possible. Personally, I would say I have three coping mechanisms to deal with the Bad Vibe, though nobody else here must (or even should) follow them:

1. A fatalistic view of the past and future. There's only one path that we shall ever experience, and so our "job" is to find the best way to react to and understand events as they come; we should not stress about all the possibilities. I do think this is literally true in a physics perspective (until the many-worlds-hypothesis is proved true, at least). This isn't to deny human agency; if anything I'm a firm believer in it, and come down on the "indomitable human spirit" side, against the "cold indifference of the universe" side. I just believe that humans and their organizations are "wielded" by historical forces and are how change comes about, whether those humans are aware of it or even hate that fact. I think there's a Mao quote around where he remarks on how capitalism or colonialism in China didn't end itself through deterioration into nothing, it was the Communist Party that destroyed it. I think that is true, but a key part of the deterioration of capitalism is precisely the creation of revolutionary organizations which will replace it. Lenin, Stalin, and Mao were wielded like swords by history against capitalism, in the same way that Napoleon was wielded as a sword by history against feudalism. Today, Sinwar and Nasrallah and al-Houthi and others are wielded as swords by history against Israel. But there are many potential swords in history's arsenal, and so Great Man Theory is still essentially false.

2. Taking a far-future view of current events. I've talked about this before in a comment months ago, where I said that one example I like is imagining some now-nameless individual who lived during the Mongol conquests of Asia - caught up in momentous events in which they heard of far-away cities being sieged and burned, not knowing if they would soon also be killed, and yet nonetheless needing to feed the cattle and harvest the fields and wash their clothes in the river and raise their family, because what other options are there? I then imagine myself, say, 300 years into the future, looking back on the events of today, when the great ongoing genocides and pandemics and horror of war has been made distant by history, where the Ukraine War is just as distant as the American Revolutionary War is today, and I imagine how little my current worries and anxieties about the future matter in the face of such large and inevitable historical forces. It's a human-centric version of when people look up into the sky at billions of galaxies and think about how little things matter down on Earth. I think that can eventually generate a sort of... antipathy towards humanity and can feed into a "humans are the disease" ecofascism, whereas keeping humanity front and center is better.

3. Trying to maintain "socialist realism", in the face of capitalist realism. This is the mechanism that most directly stabs at the heart of the problem, and so I try and cultivate a genuine belief that socialism not only can win, but that it must win. A Good Vibe, to counter the Bad Vibe. I think the best way to do this is a method that is generally difficult for people raised with the belief in taking in all information and trying not to be biased. That method is to simply and knowingly try and pay most attention to the good news, at the expense of the bad news. That's not to say you should ignore the bad news per se, but I merely use the other two coping mechanisms to minimize their mental impact. Bad events can be safely quarantined in fatalism or through a far-future lens, but good news can be fully enjoyed. Doing this is nearly impossible without decent social media discipline and requires you to give up, at least a little, on the idea that "echo chamber = bad" as well as the idea that it's your "duty" to witness suffering online despite (or even because) how bad it makes you feel. Some people, maybe even here, may fight you on those tendencies. But it's worth doing in order to have substantially better mental health in my opinion.

I suffered through fairly intense social anxiety in my childhood and adolescence, and so I eventually had to formulate and dedicate discipline to these kinds of coping mechanisms to remain functional through personal and geopolitical hardship. It's served me pretty well both irl and on this site, where doomers and irony-poisoned people are pretty common.
