Why this heated debate, guys?

Judging from above link, the car based on the 430 Scuderia could easily be converted back to a roadlegal car. I assume with enough determination and ressources, that should also work with a proper racing version but at which benefit?

A few years ago, former F1 driver Frentzen privately entered a hybrid Gumpert Apollo in the 24h race legally and the car, in its technological state, was clearly a prototype.
