The conveyor belt can't hold the plane back through the freely spinning wheels, so if it's really going to match the speed of the wheels, it has to go at thousands of miles per hour to create enough wind to hold the plane back... which will eventually allow liftoff, probably in a little more time than normal.

I think it would be far more rapid and devastating than that. Think about it. If the conveyer belt had to *exactly* match the speed of the wheels, then the exact time the plane started to move, the conveyor belt would have to accelerate from 0mph/kph (sorry, I'm American) to a speed sufficient to stop the plane from moving through the internal friction of the wheels. Obviously, we know those wheels are capable of functioning at speeds in excess of at least 200mph. I'm no airplanologist, but I'd be willing to bet those tires can take a beating at much higher speeds for a very long time. If the plane moves, at all, the parameters are no longer valid. We're talking *instantaneous* velocity change.

The conveyor belt has to accelerate from a speed of zero, to a speed that will cause enough friction in the wheel bearings, that the tires seize, in literally a zero amount of time. 

But, that obviously wouldn't actually happen, as the wheels would surely detonate in spectacular fashion through rotational forces long before friction seized the bearings. 

A conveyor belt of this capability could be the most advanced technological thing humans would ever create. Utterly preposterous.
