If you throw away food, you're wasting it. You might be allergic to it, but that doesn't change the "thrown-away food is food-waste" bit, it just explains why you don't want that food around.
You can only say whether time is wasted if you have a measure of what's a valuable use of time, and the idea that "productive" activities are more valuable than social farting around is not uncontroversial.
Food is made to be eaten, that is its purpose. So it's clear what wasted food is.
What is the purpose of a human life? There is no universal answer, hence no universal way to define what is a wasted life.
At that point, you're probably 'playing' it because of the social interaction with other people, aren't you?
I encourage people to waste their time. I was the happiest when I had free time to putz around with games and hobbies. I made stuff for the joy of it. I wouldn't wish a successful career on my worst enemy.
I don't see any utility in distinguishing between flavors of escapism. Why would productivity make a judge say one waste of time is better than another? Because that judge doesn't see the value in wasting time and the ones with creativity seem more like work and less like fun.
It's the difference between sleeping so you can be awake and putting yourself into a dreamless coma because you can't think of anything better to do. Watching TV (and not having it play in the background while you're doing something else) is the equivalent of a coma.
