One of the things that motivate people to work on academic research is the possibility of doing what you suggest should not be done. Academic researchers love reading and writing precise papers, the same way that classical musicians love to read and write complex music. Do you really think that they should measure their work by other people standards? If you don't like what academics do, just write your own layman versions intended for public consumption. Also, in many cases that is not even possible: most papers are just making a small improvement in a very complex issue, so it is very difficult to provide a concise version that is intelligible to non-professionals.
