That's a good counterpoint, I guess the obvious question is why your viewpoint is opposed.
Medical marijuana lobbyists have an easy, obvious answer: impediments are the result of a failed and ill-considered war on drugs that's actively causing lots and lots of harm. It's easy to see yourself as virtuous in that scenario.
Anti-privacy lobbyists have to go through more difficult mental contortions: large movements of people are concerned about the privacy invasions our devices represent, and that puts our future profits at risk. People are very capable of being irrational when their paycheck depends on it, but that feels too far to me.
