You mean, why didn't he write a simple compression algorithm which actually shrunk the data?
The short answer is, it was (almost certainly) impossible. You cannot compress random data. The only reason files you compress normally seem to compress is almost every file you come across normally contains some structure and therefore some redundancy.
