I was listening to a podcast this morning that was discussing the feasibility of a human colony on the moon or mars. What I am interested in was not discussed in the podcast (at least through what I have listened to), so I won't go into too the details.
Scarcity and learning
Scarcity is the foundational requirement for the field of economics. A principles of economics course might describe economics as a social science that studies how individuals and societies make choices in the face of scarcity. Others might say it is the study of conflict. Foundational to conflict is scarcity. If people were not competing for scarce resources, there would be no competition and hence no conflict.
Throughout history it has been demonstrated that free markets lead to the best allocation of scarce resources. Best in the sense that free markets optimize some sort of measurement in terms of human well being or satisfaction (utility). In a free market I only make trades that benefit me, and therefore restrictions on my ability to make those trades is sub-optimal.
Of course, if I don't have all the correct information, I might make a trade that does not work out in the end. Asymmetric information can cause all sorts of issues in markets. Especially markets not cleared by prices (like matching markets). However, I can learn from this mistake and make a better decision next time.
Governments
Ignoring my personal political biases, I think at the very least it is true that the broader the population/geography that is being governed, the less powers the government ought to have. I have less issues with my local government taxing me to pay for things that I will use or my neighbors will use. I have more problems with my federal government taxing me to pay for a problem in California that exists because California passes bad policies. The varying levels of cost of living within the US makes the idea of a federal minimum wage almost nonsensical.
Space
In the three body problem series, I think in the second book, there is a situation in which a group of humans is faced with the notion that they will never be able to return to earth. Ignoring what the author posits as the solution, I believe in a situation in which each decision is potentially an existential decision, people will want to remove their burden of responsibility. This would lead to an authoritarian style of government. What's more, there are likely situations in which decisions need to come from one person.
Tying them together
A space colony is a situation in which people are faced with extreme scarcity. Realistically, we would rely on earth for supplies for a significant period of time. Let's call this the earth dependent time (EDT). However, without the ability to produce goods, can there be a free market during the EDT? I do believe there would be some sort of market where people will trade for goods. However, I don't think a purely free market is feasible. There is a fixed supply of goods that need to be rationed to a certain extent. Maybe something like salt will be traded to get out of a chore or for a better place to sleep, but I don't know how to think about the constraints in such a situation. There is no room for mistake in an existential situation. If I make the wrong decision, it could lead to the collapse of the colony.
The other element that makes this hard to solve is that weight of the outcomes imply each decision must be highly informed. The amount of time it would take to learn the downstream effects of each decision would be overly burdensome, further limiting the success of a mission on another planet. As such, one might imagine an authoritarian type figure giving people constraints in which they can trade so as to lessen this information gathering cost.
Questions
So I guess here are my questions - does a free market/libertarian style of government make sense in space when the mistake of one person could lead to the destruction of all?
If not, what at what point do they become optimal? Is it when the system is such that one person/one decision/one trade does not pose an existential threat to certain proportion of others?
Is it some sort of gray area where one person has sole decision making responsibility for specific things and others are up for a vote?
How does this apply to reality?
