The key here for me is that treating economics like a zero sum game now makes it significantly more likely we end up at a place where it really is zero sum because zero sum thinking is nearly always short-sighted by definition, and getting to the next level requires more strategic thinking.
I've never quite wrapped my head around what that looks like. What resources could we possibly use that aren't finite?
Maybe we don't hit max utilization for a while, that happens after large innovation jumps, but there's always a cap in natural resources somewhere.
On that kind of timescale, it's far less likely we run out of energy before we can move to a new alternative (perhaps an alternative planet). You're right that no resource is infinite, so maybe the better way to phrase it is resources where we won't run out of them before we are unlikely to need them again.
In what you describe I can't help but see us stuck on a treadmill, endlessly chasing the next innovation to replace the current tech before we run out of resources. We won't be arguing about oil the next time around, bit maybe lithium?
I can't help but wonder what the point is. We could just use less and accept enough rather than constantly wanting the next big thing. I could have 10% of what I have today and still live a more comfortable life than almost all of human history.
Oil - nuclear power - renewable energy Lumber - is renewable Plastics - use less (packaging) and more renewables - but yea this is limited and we need all oil for this. Also recycling. Steel - recycling Human labour - animal power - engines - for thought - computers then AI? Electricity - renewables - fission.
There is a lot of leeway if we don't waste the resources and ingenuity and discoveries have made it a non zero-sum game.
