I don't think I'm driven to use cryptocurrencies to address any social issues. I just want to escape the rat race of working for a living. I would prefer to do things that are engaging and productive without the concern of making money.
I'm not sure I believe cryptocurrencies will resolve crime and violence. I think some crime is driven by money, but I think much of the violence out there (e.g., school and theater shootings, terrorism including both domestic and international) is simply deranged minds who somehow believe they will benefit or feel better by destroying lives and causing fear.
