Um...wouldn't a civilization far advanced in the Star Trek universe use a construction method of some sort of energy to matter? Why would it bother with harvesting planets and asteroids to construct a Dyson Sphere?

Well yeah, there is that whole point of view. The whole "ethics of a Dyson sphere" was just a train of thought from Picard, as he tried to understand the stellar fragment on a collision course and the Dyson sphere "dodging" it.
