I don't know, I like to think Eve has two skill trees, two progression levels. On the one side you have the in-game skills, spaceship command and weapon skills, that kinda thing. But those only get you so far; the other skills are ones you acquire IRL, things like fleet command, logistics, communications skills, organizational skills, etcetera.
Those can be used or applied IRL. I like to think.
Also, playing video games or other kinds of entertainment has a role in life. Sure, that energy could be applied to other, greater goods, but the fact of the matter is, nearly nobody has that kind of infinite energy supply, that kind of motivation, etc. There's a few that seem to do, which turn into people's role models - but those are the outliers. You can strive to be like those, but in reality, you'll just burn yourself out.
Relaxation has its role in life. Always has, too; sure, cavemen could be out hunting more food instead of sit around in their caves sharing stories of their ancestors, but they didn't. To name a random example.
