Because "proper" carriers were a great deal more fun, and a great deal more capable. Unfortunately we can't afford them. Nor could we then, as it happens. Anyone who remembers how everything stopped on all the other ships when Ark (the real one, not the through-deck cruiser immitation) came in to Devonport Dockyard will realise that Denis Healey, for all his sins in believing RAF lies about the location of Australia, was probably right. The RN could not afford a proper Air Arm. It still can't.
OK, tin hat on ...
