The problem with socializing risk is that you get the tragedy of the commons when some people choose to take high risks (skiing is definitely in the moderate end of "extreme sports") and pass off the risk to the "commons".
In Denmark, where health care is socialized, the argument that "society is justified in regulating activity X because we will pay for your hospital stay if/when it goes wrong" is absolutely a part of political discourse. Unhealthy foods, not exercising enough, smoking, mandatory bicycle helmets etc., it's pretty universal.
Are you kidding me?!
Even less palatable is the argument that healthy long living citizens spend more time on the labour market, generating more tax revenue.
