Re: 3 points
"Finally, I would like the opportunity, as a responsible citizen, providing I do no intentional harm to others, the right to do whatever the fuck i like in private, with consenting adults of my choice. This may include unwise or immoral or simply depraved activities, not least of which might be the consumption of illicit substances."
Problem is, doing UNINTENTIONAL harm to others is STILL a crime: negligence, and things you do in private can have knock-on effects in public, such as getting too drunk to work, leaving your boss understaffed on the day of a surprise inspection, and so on. So no, you cannot do whatever the F you like in private because no man lives in complete isolation.
