More natural resources wasted! We must preserve the limited orbital energy that our solar system has!

Theoretically, yes.

However, that would require a lot of mass. NASA would basically need to build enough Jupiter-slingshotting spaceships for their combined mass to be a significant fraction of Jupiter's. This would probably involve dismantling entire planets or moons to build that much spaceship mass.

For an appropriate value of "too much", yes. As a rough order of magnitude, "too much" would be about 10^24 such encounters. For comparison, that is about the same as the number of microseconds since the Big Bang.

For another perspective, 10^24 voyagers is about 100 times the mass of earth. That isn't even including the propellant and rockets needed to launch them all.

Yes, or about the mass of Jupiter, which is where the number came from--the article's comparison of the two.

The mass and orbital velocity of jupiter are large enough that this is a non issue.

Article too long for you? :)
