>If you accept the 3 presuppositions, the only logical conclusion is that there are no other technologically advanced species in the Milky Way or that we're the first(very unlikely).

Or they have a culture/value system that doesn't care about sprawling out to occupy as much space as possible. Why is it presumed that advanced alien civilizations would use their technology to maximize, rather than minimize their ecological footprint?

It stands to reason that environmental degradation could be one of the major filtering mechanisms for advanced life and any civilization that clears the filter will need to have fostered sustainable, symbiotic production systems rather than extractive ones.

Game theory basically. Any civilizations that minimizes would be destroyed by any civ that maximizes, so the survivors must be maximizers. Furthermore any civ that minimizes would never get to an advanced stage in the first place.

Unless we're talking about hive-minds I don't think this premise holds at all.

Civilizations that culturally value domination and expansion can dominate within their own civilization much more easily than casting out into space to find alien ones. They're more likely to destroy themselves than others.
