Can Healthcare reform change marraige?

It is not uncommon to hear proponents of gay marriage list access to health care as one of the many benefits of marriage. What happens if folks can access health care and not be married? Would access to health care change main stream ideas about marriage? Would marriage's pedestal shorten a bit if there is a public health care option?

I began with gay marriage because the use of the health care argument in favor of it indicates that health care, in part, is one of the things that makes marriage desirable. If health care becomes easier to access for non-married folks then perhaps there will be one less reason to get married. Perhaps access to health care could help us move towards untangling public benefits from heterosexual marriage. Perhaps I am too optimistic :) but if we get health care reform then we can change other things like inheritance rights.
