I agree. However, not everyone is convinced of such faults. There is still a considerable part of the current political movements that still believe that: a) neoliberal democracy is perfect, and any failure is only the fault of who has failed; or b) communism is the perfect solution, and the failures of USSR, Cuba, N. Korea, etc were only caused due to capitalist interference. For these convictions, a well developed critique has its merit, for it at least can question such certainties and unblock the way towards thinking of a better solution.
