So you either have to accept or deny the concept that people who can't afford insurance should be left to die.
If you accept it, you've made a coherent argument, even if it is morally reprehensible. If you deny it, then you must accept the fact that somebody has to pay for it. Currently, that's the taxpayers.
OTOH, if we insist that employers provide healthcare insurance, then the taxpayers don't pay, not directly, and business owners remain on an equal footing with each other, none gaining any competitive advantage.
