You're looking at it way too absolutely. The author's point wasn't to say you need to spend every waking minute creating and all other time is wasted. They/we should consider the ratio of time spent creating(and doing -- not all doing is creating), vs passively consuming. In the modern technological world, there are more ways to fill your entire existence with consumption than ever before. The point was to be conscious of that and achieve a balance, because creation/doing tends to have more lasting personal value.

The title is literally "Consume less, create more," not "Consume none, create always".
