Okay, so where do you draw the line for that? Specifically, in terms of risk to the child and defining what's "necessary"?
Obviously, I'm sure you wouldn't condone a parent taking a sick child to someone who's going to strap them to a table and perform electroshock therapy to them while they're kicking and screaming right? I think in that situation, we'd all agree that the courts would have an obligation to step in and say "whoa, that's not medically supported and it's borderline abuse, you can't do that!" -- whether the parents felt like "it was the right thing to do to fight for their child" would be irrelevant at that point.

Stories like this are why there are (and should be) safeguards.
...not to mention, you still haven't explained why this procedure in question is "necessary" to fight for the life of their child? You keep saying "do what's necessary" as if this procedure in question is a slam dunk.
Like I touched on before, only 16 people have ever received it, and it has never demonstrated any measure of efficacy. How can a $750k procedure with a 0% success rate be considered "necessary"?
Are you actually considering any of the details in this story?...or are you just trying to run everything through a "government can do no right" filter?
Your speaking like a child is "property" and not a person. A parent doesn't have right to abuse their child or subject them to significant risk or trauma with no prospects of any positive outcome.
You're desperately clinging to this narrative of "these people found a potential cure for their child's condition, and that evil godless left-wing government won't let them have it" when, as I've explained in exhausting detail in two previous posts, isn't the case here.
You even referred to the UK healthcare system as a "death panel", which was particularly ironic considering that our rates of mortality for preventable diseases is significantly higher than theirs.
