FYI “cope” is closer to “delusion used to help you cope with reality” rather than “superficial fix”

Also, I think that some strategies, such as “comfort asking a parent for help navigating a situation” are timeless defenses against strategies like blackmail. There are probably some street smarts that change and some that stay the same.

Well yes, street smart is both.

It's a temporary solution based on the delusion that you can't work on a systemic level to reduce criminal or thuggish behavior.

Ultimately I do think some form of self defense is good to know, but you can't expect it to be effective than situational.
