Mars is ~2x the distance from the sun as earth, which means about a quarter of the sun's energy reaches the surface there as does here. I don't think agriculture outside there is very viable with or without a thick atmosphere or a warmer environment, there simply isn't enough energy hitting the leaves of the plants for them to survive. But even then, I would think yes, the purpose of transforming a planet to be earth like enough to support earth life would include allowing for people to go outside on the surface. Youre right that statement isn't falsifiable, but from my perspective, everywhere that we know life is possible it exists, it's not a stretch to draw that conclusion.
