Your points about creativity aren't incompatible with the blog's points. In fact, I'd say your points elaborate the framework defined by the author. The blog defined creativity as applying mental models and combining one's past experiences randomly to discover new connections. Your points about playfulness and curiosity fall right into this framework. One who is more inquisitive will have more experiences, and spent more time analyzing these experiences. Playfulness comes with being more prone to making random connections between disparate experiences and trying to find some underlying patterns. I think this does a good job at getting to the the essence of creativity.
