Yep, this is the latest incarnation of the evergreen philosophical problem regarding technology: capabilities can be used for good or evil, depending on the designs of the empowered. One of the main arguments that governments use these days (such as the FBI re: smartphone security/crypto) against allowing "common man" to use crypto is that criminals can use it for sex slavery and other crimes. This is a good argument since the vast majority of us find sex slavery and child porn abhorrent, as well as terrorism, etc. We are likely to give up our own rights and capabilities in the name of stopping such a grotesque practice and to protect others.

That said, I'm getting to a place personally where I think we will have no choice but to either accept the absence of privacy/security, or accept that bad people will be empowered for evil just like we are empowered for good. I hope I'm wrong tho, and we can figure out a way to prevent evil use while permitting (and encouraging) righteous use.

Note: I use the words evil and righteous for illustrative purposes, not for religious reference.
