So it is not a leap to foresee government limiting health care, especially to people nearing the end of life. Medical "ethicists" have long lamented that too much money is spent futilely in the last several months of life. Are we supposed to believe that the social engineers haven't read their writings?
And given the premise that it's government's job to pay for our heath care, concluding that 80-year-olds should get no hip replacements makes sense. The problem is the premise: that taxpayers should pay. Once you accept that, bad things follow.
In the end, perhaps the biggest objection to nationalized health care is the "principal-agent problem." For whom does the doctor work? Ordinarily, the doctor is the agent of the patient. But when government signs the checks and orders doctors to reduce spending, it is not crazy to think that this won't influence their "advance care planning consultation".
Freedom is about self-determination. Obama's health care scheme would undermine both.
