Yet there is an objective difference in everything we do. You've listed a few nuances yourself; somethings are better than others. The underlying psychological circumstances are also true: There is a better, healthier way to live, feel and interact and there are many pathological, harmful ways too.
I would approach it like this and ask: "Would you rather play a game with a group of awesome friends (as hard as it may seem to find such a group, and even if that requires some effort and personality development to make such friends), or watch that streamer?"
"Would you rather have a real relationship with another person (as discouraged by the idea you might be right now) than hang out in that chatroom and pay money to a stranger?"
