The Great Come and Get It Day

Health insurance has no more place in health care provision than does car insurance in the daily operation and maintainence of a car.
Health care can and should be entirely federally financed from public funds. All providers of health care should be salaried, with appropriate incentives, under federal auspices. That would eliminate excessive provision of care because of the greed of the provider.
"Malpractice" lawsuits, which are rarely based on negligence and commonly based on undesired and often unavoidable outcomes, should be banned. That would eliminate excessive provision of services in the name of "defensive medicine".
Then all that remains is to reign in unnecessary demand by the public for excessive services based on fear, ignorance, and panic.
Also eliminate the services provided to people who are simply seeking controlled substances, or who are interested in a three day weekend, but need a note for their employer, school, or other entity so that they will not be penalized for taking it. Or those who feel they have more discomfort than would allow them to continue to work as usual.
And perhaps also limit services for those people who inflict illness upon themselves by abusing drugs, alcohol, firearms, and motor vehicles.
What about those people whose benefit from the service is marginal, like the 105 year old who would like a bone marrow transplant for treatment of a recurrent cancer?
And who is to decide, and who will enforce the decision, to deny a "medical" service based on lack of "necessity". Will they be held harmless by the legal system if they are occasionally wrong, as they inevitably will be.
Will all care be rendered as requested, then unnecessary expenses recouped by a tax levied on the abuser and collected by the IRS?
As technology advances and allows more to be done over a longer life, how will the increased cost be funded? What if the cost results in taxes on average of more than 80% of your paycheck?
Perhaps a two tiered system, one private pay and one publicly funded, would develop to cater to those individuals whose desires are not considered needs under that authority we were talking about.
But there will always be the inevitable lawsuits, anecdotes about the poor helpless soul ill-treated by the system, and the tsk tsk tsk of the media.
So it isn't all so simple as "i was sick and i needed...." or "everyone deserves...."
