I find it strange that so many cryto people get so emotional when such comments are made. It makes it rather difficult to have an actual discussion on the issues.
It's difficult to have an actual discussion when the same old platitudes keep reappearing in every crypto discussion.
I can rephrase as a question: Should we stop using groundbreaking and individual-empowering technologies just because some criminals benefit? Every single technology is exploted by criminals. I fail to see how that is an argument for its disavowal. If anything, we need to normalise privacy and encryption among virtuous everyday individuals.
