Societies have collapsed for reasons other then resource scarcity. In fact I'd say more often they collapse for reasons other then resource scarcity.
I don't think the Mayans ran out of anything. Neither do I believe the Romans ran out of anything.
My guess? The professional political/priestly/mid-level manager class gaining self serving control and cannibalizing productive (and competitive) capacity is a very common cause of collapse.
We see it on a smaller scale in companies real time.
Is this true? I thought it was drought and deforestation and over-farming that sped up the Mayan decline and that soil erosion and exhaustion and agricultural decline aided in the fall of Rome.

You could probably say the same about Rome. Once everyone in the empire could out-Legionary the Romans (the provinces were the main source of military might anyway at this point), sending tribute suddenly became a bit of a waste of time. Any disruption can trigger a chain of revolts. A revolt could be armed, or a soft revolt where the locals start acting like feudal lords and claim it's necessary to keep the peace.
Societies collapse from social factors, not just resource scarcity and social factors are in my opinion a more common cause. War, internal conflict, and political instability.
And my favorite theory, the rise of parasitic and short sighted bureaucracies which snuff out the creative and competitive impulse of a culture.
This is a bit moot, considering that resource scarcity is a very, very good reason for societal collapse, as well as potential a root cause of other reasons you cite for societal collapse, and resource scarcity is exactly what we are beginning to experience.
Perhaps you should... fuck, I don't even know. All of this information is completely free and accessible and nobody gives a single fuck because they think they're smarter.

Human ingenuity is impressive, but not infinite. I recommend Collapse by Jared Diamond. It's a long read, but every single society he examines thought they were doing great but ended up eating each other (literally) within a couple of generations once some vital resource dried up. Human ingenuity failed all of them.
I'll give you peak oil: our ingenuity is already finding viable alternative energy solutions. But climate change is going to destabilise so much more - food, water, land, security - that I'm pessimistic that our civilisation will last more than a few generations.
So far we've only discovered more positive feedback (e.g. methane from melting Siberia), when we desperately need strong negative feedback. A bit like Covid, where everyone assumed the ingenious new vaccines would get us back to normal in a couple of months, but mutations, politics and social dynamics mean we're still very much on the back foot.
But hey, I'm 60 and still a lefty so obviously no brain and just a bullshit doomer :) But do grab a copy of Collapse, there are a lot of "whoa!" insights and it's a fascinating read.
