You lack sense of ethics and you are mixing up what is technologically possible to do with something that is ethical to do.

Let me give you an example: technology like glass has made possible to sit behind people homes and look inside. You can even automate it with cameras. This is not done because there is no technology to allow it but because it is felt unethical.

In addition general population ignorance in something does not mean that more qualified people can not propose measures against unethical actions of small group of individuals. These measures can be then formed into another invention called law and applied by another invention called law enforcement.
