Velocity is a vector, not simply a rate. Launches and orbits are three-dimensional.
What would be a great technological achievement would be launching from French Guiana (5.2° N) and then making a plane-change maneuver to achieve a polar orbit (90° inclination). All that bonus eastward velocity from the Earth's rotation would turn into a penalty they'd need to compensate for no reason, when they had a spaceport more suitable for that polar inclination.
