There is nothing we need on Mars other than science. It's not a market because there isn't money to be made outside of what is required to do whatever economically useless but scientifically valuable efforts we can convince people to fund.

We can't build an independent colony we can't live there any time soon. Arguably it may never make sense to live there.

With that attitude mankind would still be living in caves. Why build a farm and stay in one place - we should follow the animals around.

1. Mankind never systematically lived in caves; that's just where remains and rock paintings are more likely to have survived.

2. Farming didn't evolve from a vision of "let's stay in one place, so let's find a way to do it"; it evolved from the gradual application of accumulated practical knowledge under real constraints until eventually it was possible to stay in one place. If Paleoelon had somehow convinced early humanity to abandon hunter-gathering and settle into a sedentary life because he had a vision for new markets around farming it would have led to the earliest famine.

While what you say is mostly correct, the lifestyle switch to farming was determined not by some random gradual accumulation of knowledge during the previous million years, but by accelerated accumulation of knowledge during a few thousand years at most, which was caused by the dwindling hunting resources, which forced humans to abandon the lifestyle that they had for a couple million years and switch to a lifestyle where the staple food consisted of plant seeds, with anything else providing much less of the nutrient intake. Only after a few more thousand years, raising domestic animals allowed the return to a more diverse diet.

Switching to a farming lifestyle was certainly not done by choice, but to avoid death by starvation, as we now know that this has caused various health problems, especially in the beginning, presumably until experience has taught them to achieve a more balanced diet, by combining at least 3 kinds of plant seeds, 2 with complementary amino acid profile and 1 kind of oily seeds for essential fatty acids (the most ancient farming societies have combined barley or einkorn or emmer wheat with lentils or peas or a few other legumes less used today and with flax seeds).

Yes, your description of how farming and sedentary lifestyle progressed is much more accurate than my somewhat clumsy attempt. My intention was to emphasise that such a transformative event in human history did not take place thanks to visionaries going against the grain [0] , but rather through a long and complex process.

[0] Well, technically in favour of the grain! Pun not initially intended: https://en.wikipedia.org/wiki/Against_the_Grain:_A_Deep_Hist...

Define systematically?

>>esseph+AD1
In this context, 'systematically' is a qualifier to the adverb 'never'. It serves as a disclaimer to avoid someone pointing out that, well actually, some humans have lived in caves and do so to the present day.
