Ask Ethan: Why don’t we shoot Earth’s garbage into the Sun?

Slightly unrelated, but I wonder if in a scenario of the distant future where we routinely slingshot massive spacecraft in and out of the solar system (to slow down or speed up), could we ever reach a point where this activity would significantly affect a planet’s orbit? (Though I’m sure it would be fairly easy to cancel out the effects by alternating the ejection points between the front and the back of the planet.)
