It's not even a thought experiment, it's a philosophical debate on morals and laws vs freedom and whatnot. It's not an easy one, and it goes back decades if not hundreds of years; remember things like the Anarchist's Cookbook?
(Sidenote, there's a conspiracy theory that the Anarchist's Cookbook is intentionally wrong with some formulations to foil would-be bombers)
- How to make a baking soda volcano
- How to make legal drugs at home from scratch (this violates patents)
- Explaining how a fictional character in a popular TV show created the drugs shown on screen
- Giving you the titles of legally sold books that explain how illegal drugs are made
It's an interesting thought experiment.
