I think that's somewhat different because in Ancient Greece there was extreme decentralization. Cities were sovereign entities with an extreme diversity of ideological and other values. Compare Athens and Sparta, for instance. And so in this system, if one stays in a city then there is a strong argument to be made that they are implicitly supportive of the laws and rules of said area.
In modern times this isn't really the case. There tend to be immense legal restrictions on movement, let alone living + working in different areas. And the differences that do exist between even nations within the same "sphere" tend to be relatively negligible compared to, again, the sort of monumental differences you'd see just between different Greek city-states like Athens/Sparta.

There were extreme legal restrictions on movement in Ancient Greece, too. You couldn't just pack up your bags and move to Spara or Athens and become part of the citizen class.
And as a non-citizen, there were a lot of different ways that you could be abused by citizens, with little recourse.
Just because despotism and abuse was decentralized, doesn't mean that it wasn't despotism and abuse.
