What else could it even be? You started your gotcha with the truism that it's not free, so, yeah, nothing is free, and the whole discussion is meaningless. You're arguing in bad faith, but that just makes your argument meaningless.
> no current Earth society comes close to that criteria. For example, if someone has a currently untreatable disease
Your counterargument is that there exist diseases that cannot be treated anywhere?
Let me give you an example of something treatable: Endemic (flea-borne_) typhus. In Europe, the given example is "British POWs in Germany at the end of World War I when they described conditions in Germany." [1] In the US, instead Typhus shows up in the reports of the LA Medical Association as a regular occurence (among homeless, mostly). [2]
