Well, to be honest, that universal in many developed nations. E.g. in Austria it's attached to all kind of things, e.g. employment, benefits, but in theory (although it's rather hard), you can be privately insured. Even harder, but even that is possible, to be not insured at all.
So in effect, healthcare (and social security, all kinds of benefits) are universal. There are literally very few forms of income without “payroll taxes” attached, rent income mostly.
