In my view, it's more important to vociferously reject and squelch such discussions that revolve around limiting personal freedom for the so-called public good, especially when the benefit to the overall public good is so insignificant.
"If we can save just one life...." is something anathema to people who greatly value personal freedom.
If I understand you correctly, your suggestion is to pro-actively have the knowledgeable or invested participants assess the safety of the activity because it will head-off the inevitable attempts by those who are less expert or invested.
Unfortunately, the pro-active approach will have the negative consequence of validating the insidious premise that the public has a right to regulate the activity in the first place, even though it is practiced by so few and has such little impact on society.
Such a well-meaning premise needs to discredited at every opportunity, otherwise it will continue to be expanded by those who feel so good about themselves to have taken care of others, even when it required limiting the freedom of those others to protect them from themselves.
We should counter the attraction of such "feel good" public policy rationale with a resounding and vehement public rejection until the idea of taking away personal freedom becomes the last thing considered.
