“Rocket fuel provides a fixed impulse (‘delta-v’) and not a fixed change in kinetic energy.”
For most people, intuition conflates the two, and understanding that they’re different adequately explains the effect.
Of course there’s a perfectly correct explanation for it all reference frames, but the frame of the planet is a good choice.
What you’re doing sounds to me like saying “I don’t think the concept of centrifugal force is intuitive. I shall explain, say, how roller coaster loop-the-loops work without using it.”
