>Otherwise very nicely put, but surely there is a useful distinction between "not getting what you want" and "oppression"!
Wants themselves do have ranks, as does the amount of oppression felt by not getting them. As you can imagine, there are likely some people who want 2nd vacation homes, but would prefer not having a 2nd home over not having food if they were ever forced into a situation where they had to compromise. But it's not as black and white as you'd might think. People don't all share the same wants, let alone to the same degree. There are people in this world who would prefer to own 3 homes not caring that there are homeless people wanting just 1 (greed). There are people out there who prefer to go without buying food, dumpster dive, and work minimum wage jobs despite having better offers, all in order to save up to buy a house (I personally know a guy - and this is pride). People who like to go without food (ie fast) for weeks (me). And yet, people who prefer to remain homeless, people who want to help the homeless, and people who don't want to help.
>If every loss is oppression, then winning becomes a moral imperative, possibly requiring escalation to violence
Whether something is a moral imperative is subject to opinion - whether you personally deem it so. But yes, especially at some extreme point, that is reality, and you cannot escape it. This is exactly the sort of thing political philosophers such as Hobbes and Locke argued in their social contract theories. It's why when loss is deemed to be so terribly bad under tyrannical governments, that there are violent revolutions. It's the reason for wars. It's literally what lead to the foundation of the United States.
That said, you can learn to go without most wants. It's what Buddhist monks teach and practice. Additionally, wants have ranks, as I mentioned above. So winning is not always a moral imperative for everyone in every case. Some people simply don't care that much about certain topics, and don't care if they lose the outcome.
>No-one wants to live in that world
Yes, that's why true Anarchy doesn't last long. Anarchy, or the state of nature, can often be brutally violent. Wild animals often kill each other just for fun, it's called surplus killing. Power hierarchies naturally form within same species, just to avoid constantly having to violently fight to determine the outcomes for conflicts. The suffering of being subjugated is often preferred to the suffering of being violently maimed (or mere risk of it) by your neighbor, but pushed to a point it can obviously flip, leading you back into a revolution. As you put it, no one wants to live in that violent world, (at least not very long), so a hierarchy eventually forms in order to avoid having to live in it.
>Aren't we ALL kind of in the same boat with respect to climate change ...
Yes and no depending on how you look at it. Do we all have opinions on those topics? Yes. Do they affect us in some way? Yes. Do we all share the same opinions over them? No. Do we all rank those issues at the same level of importance? Probably relatively to some degree, but ultimately no.
