Of course you can vindicate your rights. The main problem is that it is usually not practical or cost-effective to do so. Ultimately, rights are manifested in a court of law. And this is an expensive route that involves hiring a lawyer and paying legal and court fees (money which put be put to better use towards satisfying lens lust ha~) assuming that you have a course of action in the first place.
That's why we need an ACLU-equivalent.
