Why don't you believe in a free market for health insurance? Forcing
people to pay into a health insurance is kind of scammy - let's say
that I have a genetic condition that is certain to kill me rapidly at
age 30. I want to live my life to the fullest, and I'd rather not be
forced to buy health insurance that protects me from things like adult
onset diabetes, alzheimer's, cancer, parkinson's, etc, that I'm just
not going to get. Why should I be forced to pony up for other people's
healthcare, too? What do I owe those bastards who get to live twice
as long as I am and beat me up and teased me on the playground in
middle school?

The more insidious thing about universal healthcare is that it really
screws over most minorities. Minorities tend to have diseases that are
not as well researched as those found in ethnic majorities (or certain
minorities which are disproportionately represented in the medical
research community). Moreover, drug testing -for safety and efficacy-
in minorities is very scant, and it is sometimes the case that adverse
reactions to drugs occur in minorities that do not occur in the ethnic
or racial majorities. Of course to find that out you need
statistically relevant sample sizes, and the way drug safety testing
is done is by recruiting on college campuses - you can see the
potential problem here - and even still some minorities that are
overrepresented on colleges are, for whatever reason, underrepresented
in testing pools. So as a minority, one might be paying into a system
that disproportionately treats diseases that one would not be getting,
or with different pathologies, and for which the treatments may be
completely ineffective or even dangerous due to lack of study.

Then there is this problem. What if those who decide health coverage
decide that heterozygous genetic condition X is covered (and it's
expensive). Two parents who are carriers now can decide, hey we can
afford to have kids - after all it's their right. So now everyone is
saddled with the burden of their selfish choice. Or, we can restrict
their liberty by prohibiting all such pairs of parents from
reproducing. Whereas if they are responsible for the cost of their
children's care, then the simple answer is they might think twice
about having children and if they are foolhardy enough to, there is a
1 in 4 chance they get dinged with the cost of coverage.

Ultimately, any governmental (i.e. non-free-market) health insurance
plan must either explicitly discriminate between individuals or, if
universal, implicitly discriminate between individuals. The perverted
consequence is, ultimately, going to be a transfer of wealth from the
poor (via inflation) to those who have the right genetic
predisposition to conditions which are decided to be covered by the
powers that be.

Keep in mind that 'free market' != 'for-profit'. You can have
nonprofit insurance companies, and healthcare charities, in a 'free
market' system. What free market means is that the consumer has a
choice of where to go for their services. If you are saying that you
don't like 'free market healthcare' you are saying that in the
aggregate, the population is too stupid to make responsible,
cost-effective decisions about their own health. If that is the case,
who or what group of people could possibly be so enlightened and
all-knowing to correctly orchestrate all those choices from the full
society on down to the individual level? And how might we shield
society from the hubris of our godlike health chancellor/council?
