Have you imagined what a near-future Mars colony will be like? You can't live on the surface, so it will be as high-tech and enclosed and cramped as a space station; an air-tight pressure vessel with no escape. It will have limited energy and resources so there will likely be rationing. It will be vulnerable to any pressure breach or loss of power, so can take no risks with mechanical failure, bad actors, disease spread, etc. so it will likely be sensored and surveilled all over. It will likely be funded in large part or entirely by private investors. Musk has estimated $500k for a ticket to go there and people have estimated $3Bn/year for 30 years to keep a base running with no economic return from that.
No government, no police, no Wild West "run them out of town" option. You think they're going to want to spend $500,000 return flight cost to send potential criminals away or just "let them be" in an environment like that?
The idea that you might be able to go there and "demand your freedom" without being a billionaire owner of the colony is ill-thought-out. Subjects will have no leverage and no options, and leaders will have billions sunk into it and demand obedience like a Navy Submarine.
