In societies that have a duty of care to individuals, I think it's fair to believe people also have a reciprocal responsibility to take reasonable care of themselves. For example, in theory not wearing a seatbelt is a purely personal decision. In practice, that decision can have considerable negative externalities - impacting family, friends, emergency and medical personnel and finally the taxpayer (I live in a place with nationalised healthcare), etc etc. Similar problems play out (statistically if not on a personal basis) with respect to drug use or other risky decisions like going into deep bush or out on the water without adequate precautions. If there's a reasonable expectation of not being shunned and left to die alone in the event of a mishap, I'd hope that home experimenters would spare a thought for those who will no doubt help care for them and deal with the mess if something goes wrong. That said, I expect and understand that reasonable people can hold quite different views on where the lines between social responsibility and individual freedom should be drawn.
