It’s still a lot cheaper than instantaneously cancelling angular velocity.

Yes the source of thrust is still cheaper using a launch window. Basically, you don’t need to kick directly to the sun you just need the child to land somewhere below a maintainable orbit given their velocity. The closer they get the more gravity will effect them and do more work that we don’t have to do.
