But couldn't a finite system be configured and reconfigured in such a large number of ways that to all intents and purposes the possibilities are infinite? What if "growth" is about creating better and better knowledge of how to configure the system in more and more valuable ways?

No because there are unbreakable physical limits. You cannot turn a finite system into an infinite amount of resources.

We are nowhere near exhausting the resources we have available.

We are also nowhere near optimal efficiency when using resources.

the externalities of resource use are arguably reaching catastrophic tipping points that will hit before depletion is an immediate concern

> catastrophic tipping point

This is pretty funny as people have been calling for some kind of human-caused apocalypse since forever.

It must be human nature for some to believe such things. To see ourselves as inherently sinful, wicked, separate from nature and deserving of punishment.

Climate alarmism has become a religion of sorts for many. Giving them maybe something to believe, maybe some purpose. At least something to talk about.

There are countless other religious sects that also believe judgement day is “right around the corner”.
