This is from Nick Neuman at Casa. The general concept is spot on: if it was known that most Bitcoiners used multisigs, wrench attacks would probably be less common.
However, I'm not sure his argument is the best. Neuman argues that one of the main reasons home burglaries have dramatically decreased from the 1990s is an increase in the prevalence of home alarm systems. While this may be true, I suspect another major reason is that fewer people keep piles of cash in their house, and most of the portable, high value items are becoming harder to sell. Feels like every pawn shop requires ID these days. Maybe I'm just not deep enough in the criminal world...
Wild chart though showing the increase in extortion attempts on crypto holders in general:
