70s theory.
Fluid dynamics are better understood and creating an integral lift from the body proved more effective than separate wings. Combining the body flow and the wing gave a better over result.
BUT, the real reason the tall wings were made illegal was the willingness for the supports to break - no mater HOW strong they made them, they were breaking. Losing THAT amount of downforce was VERY dangerous back then as the understanding of under-body airflow was so crude that these things were flying wings ( unlike todays inverted wings )
