True, but it might allow the freedom to implement alternative methods that clamp down on such things. Just as the New World allowed for the political innovations that has lead to modern democracy (however flawed), Mars would be a new frontier that could be used to create a better government with all the lessons the past 400 years has taught us. It would be an even better frontier, as Mars doesn't have the pesky problem of people already living there with all the historical baggage that accompany it. It doesn't have the terrible legacy of slavery and the social problems that that implies. It is a fresher start than we as a species have ever had, and we now how the proper perspective to avoid the pitfalls that we're currently saddled with. In time, much as democracy filtered its way back to Europe, a better system of governance could find its way back to Earth. In any case, it would be a bold experiment. To go in with the intention of building a better social contract, or to rethink what that even means, is something that we should keep in mind. Mars shouldn't just be a joyride in 0.4 g, but an intentional effort to rethink society.
