That's a valid point, but it's worth pointing out that it can be applied to many more things than just marijuana (TV, video games, alcohol, social media, most articles people read, many apps, etc.). There's an enormous section of our economy that's devoted to wasting people's time when they could be "learning some new skill or discovering some new science or being creative" (I'd add taking care of your body, your mind, and your community to that list as well). For a lot of people, evenings have been the time to sit mindlessly in front of a screen for a few hours. This ends up hurting our society on multiple fronts: people not being as productive as they could be because they're encouraged to waste time, an overall less happy society, a less healthy society because of the encouragement of sedentary behavior (and the economic burden that comes with that), a large part of the economy that could be devoted to improving people's lives but is instead wasted on encouraging negative behavior, etc. The problem is that we've grown so accustomed to this situation that we rarely think much about it, or what we can do to change it (whereas marijuana is getting at least some scrutiny, since legalization is new).
