Reply to comment by Enterovirus71 in Artemis is cool, but there really isn't a good reason we're going back to the Moon (or to Mars and beyond). by [deleted]
The self limiter is not a civilization. It's more or less just an extension of the same forces that balance out the biosphere that gave rise to us. I'm not sure how Kurtzgesagt described it but that's how I think of it.
And you do sort of see this self limitation all over the biosphere. Anytime a population exceeds the carrying capacity of its biosphere, hunger and disease, etc tend to self limit that population back down to the carrying capacity.
It's not really an active agent rather more an artifact of a limited biosphere. Technology kind of lets you ignore that for a time but essentially you're just building a bigger bust into the situation if you rely solely on technology to save the day. Temporarily.

Oh, for sure. I just don't m know what this self-limiting natural force would be. If you keep exploring new planets and stars, thus garnering unimaginable resources and energy, it's hard to imagine that the ecosystem would work against you in some mysterious way. The limiting factor, in my opinion, will be cosmic forces, i.e., the redshift. We will eventually be confined to a small sliver of the universe as the universe expands and the distances between galaxies become too far to for intergalactic travel. My point is, the limitation does not have to be catastrophic. It can merely be an endpoint in exploration when we realize that expansion would no longer be possible due to distance constraints.

Take LEO for example. It's a limited resource.
And if you just blunder into it willy nilly and go full colonial mode on it, you could lock yourself out by having just a little war or a lot of capitalism treating it as an externality. Either of which could lead to Kessler.
That would be one form of space based self limiting. You basically create the very trap that keeps you locked on your own planet.
And I get that the limitation doesn't have to be catastrophic. In fact, as a self aware species with a great deal of intelligence and the foreknowledge that actions have consequences, we or other civilizations could possibly make the adjustments necessary to prevent a catastrophic limitation.
But that requires going against the things that got you to that point in the first place (giving up conquering and colonialism to get you out of your biosphere deficit and embracing a lower energy, symbiotic lifestyle...though I'm not sure if that's even an option at this point...i like my lifestyle just as much as the next person).
So it's probably a really tricky spot for most civilizations that get to this point.
