There is not enough space for 8 billion humans to do "frontier living."

Not to even forget how unstable that sort of living is. A few bad seasons from various causes could really affect population. Just look at history of famines. It kinda works when you have industrialised agriculture in other places to fallback on, but without that it is very risky in long term.

It always intuitively felt to me like there was enough space, but I am now getting the sense that my intuition here has been wrong.

Will you define "frontier living" so I can better see the lack of space ?

One crazy thing I recently heard that put this into perspective is that Livestock makes up approximately 60% to 62% of the world's total mammal biomass. Combined with humans (approx. 34%–36%), domesticated livestock means humans and their animals constitute roughly 96% of all mammalian biomass on Earth, leaving wild mammals at only about 4%.

I suppose Frontier living doesn't necessitate hunting, but the amount of readily available meat and animal products would have to drop very low.

I assume they're referring to the inability of small scale agriculture to produce as many calories per acre as our current food system, which also relies heavily on fossil-fuel based imports. Of course, we also have a lot of unnecessary (but tasty!) excess in our current food system too.

I think the problem really becomes - what do you do when the current system becomes untenable? If the costs of a "basic" modern life (housing, transport, food - I'm not even including healthcare here) become impossible for someone on the median income to have, then what, exactly, are they supposed to do? Find a nice corner to die in?

We sorta tried a miniature version of this on a few acres in Ireland and while it was tough (and we were always reliant on the outside world, we didn't literally homestead), I'm not sure it wouldn't be an improvement for a non-trivial percentage of people at the bottom levels of society.

But, of course, land is owned (thanks to enclosure, which took a common asset and allocated it to specific individuals), and this all falls apart when you or a loved one have a serious disability or illness.

I appreciate the nuanced reply and yes, I do mean that you will not be able to produce as much food as you currently can nor will you be able to do so as reliably as we currently can.

And while you might be able to do it in Ireland — one of the only countries in the world with less people than two hundred years ago — it will likely be impossible to the billions living in far more densely populated countries.

		I think maybe there is a "frontier living" fantasy that is resting on the hidden assumption that you can bring your modern tech stack with you, minus the civilization that it relies on. If I squint my eyes and imagine really hard, I can see living off the land, supported by small fusion reactors powering powerful AGI computer clusters, highly advanced 3D printers capable of producing all the physical support structure of life. AGI + Power + Magic 3D printing and maybe one can live "off the land" with "civilization and all of human knowledge" hiding inside this portable tech stack.

		Very true, and I worry that as the planet heats many of those billions will die

Water for one. It was very risky as things like droughts quickly killed you. It was also very risky as someone moving upstream of you and shitting could see you dying from dysentery very quickly. Water is in far worse shape now because of how deeply we've pumped out aquifers and how poor we've left soil conditions in many places.

Next is amount of people. Current human density is supported by antibiotics. Take away them and we quickly fall back to around 1900 population density (1.6 billion roughly). And not even internal antibiotics, external antibiotics like chlorine for cleaning and water purification.

So those are the setups for population collapse. When population starts collapsing this way it generally overshoots the numbers pruned because of war/disease. We won't fall to 1.6 billion, it's likely to fall well below 1 billion.

Sure, but there might not be enough jobs for them to command the economic power that allows something better.

Even so for someone who's been crushed in the gears enough they might give it a try.

They can manage it. Cheap drugs, distributed by the government, can handle you from suffering and ensure you will not participate in any kind of anti government protests. Also they can add birth control additives and reduce the population significantly.
