Ride the Wind, you have to move the unit right, you can't just ready and not move?

No, you can't just ready it without moving. Ride the Wind says "Move a friendly unit and ready it" — both actions are part of the spell's instructions.

Per Rule 355.4.a, the destination you choose must be a location other than the unit's current location. FAQ #10933 directly confirms you cannot target the same spot. And FAQ #9277 adds that you cannot voluntarily ignore the move instruction if a valid destination exists — you must move to a different valid location.

The readying happens in addition to the move, not instead of it.
