the motor was built to hold 7000 so what makes you think it is going to hurt it to take it there, sure yeah if you do it with no load/ over and over and over again 4 million times a day like me then yeah it might hurt it.
You may want to look into replacing the clutch and rebuilding the engine soon. Driving like that doesn't hurt the car, but it will cause failure quicker if the mechanics aren't 100% to start.
