Park the car with the front tires on two pieces of cardboard (each) to limit the turning forces.

I wouldn’t sweat it for the duration of demo or until you (quickly) got bored with it. You do the same everyday you parallel park a car.

Dry steering will also damage your concrete or pavement. Should probably jack your car up while doing this or turn up the sensitivity so very small inputs translate to larger turns

It will damage your tires more than the concrete.

Concrete, yes. On the other hand, a hot residential asphalt driveway can be boogered up pretty easily.

Or just on jack stands
