That spaceships can escape Earth’s gravity makes gravity sound more like a force that can be opposed by a greater force rather than a property of spacetime geometry.

Gravity curves space. More mass gives more curvature.
The Earth is curved, but this doesn’t keep us from sailing around it. Yes, it’s more work to escape a gravity well than just coast between points in empty space, but that’s what rocket engines are for.
