The better question to me, though harder to answer, is whether I would consider their activity immoral. I would be happy to proxy traffic regarding investigative journalism, queer sexuality, consensual pornography, even though it is illegal in many places.

Or even drugs, why would I want to punish people for smoking pot after a long day of work? Why would I want to take control over what they can or cannot do to their body? You have no idea how many people are out there with chronic pain without access to proper painkillers. Additionally, drugs are a means to an end. It may help with physical pain or emotional pain, anxiety, depression. It may help with socialization, being productive, ADHD and so forth.
