This is the same problem with cheating on tests and homework. By making getting a higher education degree mandatory for entry level jobs to be able to afford a normal life, people are incentiviced to get the degree, not the education. By tackling this particular case of students with fake disabilities, the universities will hurt people with real disabilities. Same thing with anti cheating measures that affect people that don't cheat.
The root case of all this is making degrees mandatory on our society.
