Seems like they’re skipping a lot of derivation steps here. Almost as if they somehow secretly knew which ultimate destination they wanted to arrive at, and were using the excuse of imminent starvation to immediately propose that solution as if it were the only possible one.
There is a key skill taught in dath ilan, called in Baseline 'blahblahblah' -
Actually Keltham did queue a Share Language (Communal) today and might as well use it so he can, at the very least, use words like that one, and have people hear the meaning as well as his definition. Gather round, tap tap tap, you all have Baseline for three hours.
There is a key skill taught in dath ilan, called in Baseline 'perspective-taking', which is about carefully controlling your own mind to operate as if it were somebody else's mind, putting yourself into their own shoes and mirroring them in order to simulate them accurately. In this case, they're being asked to simulate somebody who does not know, who has had forgotten and erased from their mind, what it means to own a thing. It is not, if you take that perspective properly, like unto the experience of looking at things, seeing no ownership tag on them, and jumping from there to the conclusion that other people might grab those things and own them, or fight over them and own them. You just see things, they have shapes and colors but no property of being owned, that concept has been erased from you.
We're not asking "how do people reinvent ownership". They don't know they're trying to invent ownership. They're just pondering the question of how they might avoid starving in a couple of years.
They might imagine that people need incentivizing to work on the farms. Why jump straight to the conclusion about rewarding them with 'ownership' of the grain the farms produce? Maybe all the grain goes into a big grain storageunit, and they guard the perimeters of their land to keep out strangers, and only people who worked on the farms are allowed to wander into the big grain storageunit and take grain from there, but they still have no concept that the grain is tagged with a property of being owned by anyone, even themselves collectively. They're just working to grow grain, and guarding it.
The idea is not that this is a better solution but that it is a simpler solution that seems to maybe solve the immediate problem of people starving in two years. Somebody thinking about just that problem, who didn't have a concept in their minds of 'ownership', might come up with this simpler solution that apparently solves the problem of immediate starvation in two years, before they invented anything as complicated as ownership. It would take some more difficult problem to motivate that one.
