Decades ago, there was a proposal that there should be no-rescue zones for backpackers, in which backpackers would be entirely on their own, and rescue by government agencies would not be permitted. (Private rescue operations would be permitted.)
See, for example, this 1984 article in Backpacker You're Losing Your Right to be Alone.
As I recall, the principal objection was, to put it crudely and sexistly, no agency could resist the pleas of a tearful mother whose son was lost and possibly seriously injured. Public outcry would force government SAR.
Did this proposal just fade away? Or was it never really taken seriously?
