Clutches are designed to wear and be replaced, like brakes.
The wear is not so bad but remember the drive efficiency from wheels to engine here is under 50% (50% at the clutch because it's slipping, plus transmission losses). I'm pretty sure you'd save more fuel if you used the gas pedal to rev the engine up.

Plus, the jolt is probably bad for the transmission.
