Or, in a more positive framing, our society pays for the negative externalities of our more risk oriented members doing rad shit.
I am happy to pay through taxes for things like rescue services or medical bills for people who do things like rock climb or attempt ocean crossings in a solo kayak. Or even just ride a motorcycle without a helmet and look awesome.
The world is better and more interesting with these people in it.
I suspect that those riding without helmets might actually be cheaper to treat. If you survive an accident but get your foot degloved, and you need an amputation and a prosthetic and months of physical therapy, and then a hip replacement years later because of your messed up gait, that's a lot of taxpayer money. If you die on impact, treatment is much cheaper.
