This unproductive argument is exactly what's wrong with your Pickett's Charge case against the ethics of insurance as oppposed to "cost pooling". People who disagree with your slippery slope argument will just put you on their own slippery slope; pretty soon you'll be arguing that yes, it's only fair for us to be buying everyone's kids X360's.

There are plenty of pragmatic problems in the current system to address arguments to. The solutions to those problems will improve people's lives without requiring anyone to adopt new political ideologies.
