Governments do one thing and one thing only - wield power. There is no such thing as a benevolent government. Governments only appear somewhat benevolent because they haven't yet completed their journey to tyranny, but they are all headed in that direction! So, be very afraid of any power you grant to anyone, and even more afraid of power given to a group of people.
What brought on this mini dose of absolute reality? The story of little Charlie Gard, a British infant the British government wants to kill. Despite the offer of a U.S. doctor to use a new experimental procedure that has some possibility; despite the raising of private funds to pay for it; despite the offer of Congress to grant citizenship to little Charlie to expedite his trip here; and despite some physical evidence to suggest there's still "something there" inside little Charlie's head, the British government wants to kill him.
Why? Two reasons: Them's the rules, and because they can.
Still want the government to have a role in health care? Well, pardon me, but you're an idiot.
