If groups share common values and purpose then social cohesion is higher.

In our terribly over-regulated, over-taxed world many groups of like minded individuals will form their own groups, buy a 2nd hand Starship and form their own colony, free from the evils of government & the need for complex laws.

I can see Cypherpunk groups, religious groups & groups with alternative social & political structure they want to try out without interference being the earliest private settlers on Mars, just like they were in the early USA.
