You've put up up a good defence of having GTs only but the fact is if you only had GTs (as in FIA GT), the manufactuers will still build prototypes and homologate them for the road.

Just look at GT1. Nobody could compete with the F1 GTR so the only option for rivals was to produce 'prototype GT1s'. Look what happened to GT1 racing then. The arrival in GTS of the Masarati and the like could result in a similar situation occuring (although I think the safeguards are in place to stop this happening).

You have to keep prototypes in order to keep GTs stable. Bentley would have to build a 'prototype GTS' to win LM if prototpes were banned and this would instantly mae obsolete the Vipers, C5Rs etc.

Sportscar racing learned its lesson in the 80s/90s not to have all prototype or all GT grids. A mix, as has always happened previously, caters for everyones needs. Porsche can race the GT3 in GT, Carrera GT in GTS and a prortotpe for overall wins.

As for prototypes not being adentifiable by the public, well my dad, a none racing fan instantly knows a GT40, 917, Jaguar Group C. This is due to good advertising and success on the track. He wouldn't know what a Zonda or Spyker is.
