What makes them so difficult is that they involve two contradictory impulses on the part of a person's family and others with a financial stake in the outcome of the medical care.

I think the question here is one of who makes that decision, the family based on their beliefs, or the state. The decision is clear to the Brodys, this is not prolonging life "unnecessarily", removing him from life support would be killing, not necessarily murder.

Shouldn’t the decision be made by whoever is paying the bills?

This is why the state should never be involved in medical care in the first place. Once you turn over the financial responsibilities for your medical care to the state, you will always run the risk of having the state make some very calculated, pragmatic decisions like this.
