Buddha addressed this idea directly. Your instinct that "getting comfortable with nothing" is still doing something turns out to be exactly right, and Buddhism doesn't deny it. Its answer is basically: yes, you use one kind of wanting (the motivation to practice) to loosen a deeper kind of wanting (craving a specific outcome), like using fire to burn down a house, then the fire has nothing left to burn.

Meditation, in the Therevada tradition at least, never claimed to be nothing, it uses doing to undermine it.
