The bolded parts answer the part in red and bold. People, I think, are too afraid to go at it alone. Even the "rugged individualism" upon which this country is founded is somewhat of a farce in that these people relied on families and other friends. Consider the Oregon Trail...they didn't ride alone.
A truly free market is anarchy...and few reasonable people want that.
Social contracts are important because of the insurance they provide. One is free to go at it alone without such concern for the social wellbeing of his fellow man. However, few reasonable people wouldn't instigate relationships as a backstop in the event of a free-fall.
Because I believe man is naturally evil and selfish, I cannot agree that gift and reciprocation is no more of a natural state than the one that requires people to think rationally. The advantage of the "regulated capital" state is at least one knows the rules.
I would argue that man, by nature is a social animal. We are not solitary creatures. We have evolved dependent upon each other and social contracts.
We have a much longer history with a system that was not based upon a free market but other principals:
Redistribution is involved where a chief or leader gathers together a harvest or the kill of a hunting expedition into a safe storage place. Having made it safe he then redistributes it to members of his group by holding communal feasts and festivals. This serves both to share the communal wealth fairly, and also to reinforce the social structure, allocation (and indeed seating arrangements !) indicating status and importance. These festivals may also be used to reinforce relationships with neighbouring tribes, and the store may be used to supply the community's warriors if circumstances require (Polanyi 1945 50-56).
Polanyi recognised that market places existed in ancient times, and were present in primitive economies, but he argues their existence away by saying they were not important, and existed within a context of reciprocity. Money too was often present, but it was unimportant, and also operated within the context of reciprocity. These money using daily markets were merely convenient localised exchange places operating within the broad system of reciprocity. There were also market places for long distance trade, such as ports. But these were only for items which could not be obtained within the area, and therefore could not be provided within the local system of reciprocity. These 'ports of trade' were specifically isolated from the prevailing reciprocity area and served to separate it from external influences. So local craft and provision markets were not linked to long distance markets and the 'ports of trade' were controlled by the authorities to ensure the isolation was maintained (Polanyi 1945 64-69: See also Polanyi 1963 30- 45).
If ancient and primitive economies had market places but were not market economies, how does Polanyi define a market economy ? How is it different from a system of reciprocity ? According to Polanyi, a market economy is an economic system controlled by prices, these prices determining how much is produced, and how what is produced is distributed. Social considerations have no part in this system. Money exists, which serves as purchasing power and enables its possessors to acquire goods and services, which are priced in money terms. People are motivated to acquire money with which they can then purchase whatever they want (Polanyi 1945 74). Polanyi believes this monetary based market economy sprang suddenly into existence in the nineteenth century thrusting aside the old systems based on reciprocity and redistribution.
To return to Polanyi's basic point, he argues:-
''The outstanding discovery of recent historical and anthropological research is that man's economy, as a rule, is submerged in his social relationships. He does not act so as to safeguard his individual interests in the possession of material goods; he acts as to safeguard his social standing, his social claims, his social assets. He values material goods only in so far as they serve this end.' (Polanyi 1945 53)'
I choose to sell myself on the open market. I choose to acquire skills and sharpen my mind so I can compete with others to acquire materialistic goods because I am selfish. I do not believe there is anything particularly important about being a human vs. a cat or a tree.
What other choice do you have?
I believe there are substantial qualitative differences between a human being and a cat. If you deny these are important you are denying your humanity, which separates you from the majority.
