If we want to go that road, intuition is according to Wikipedia:

Intuition is the ability to acquire knowledge, without recourse to conscious reasoning or needing an explanation.[2][3] Different fields use the word "intuition" in very different ways, including but not limited to: direct access to unconscious knowledge; unconscious cognition; gut feelings; inner sensing; inner insight to unconscious pattern-recognition; and the ability to understand something instinctively, without any need for conscious reasoning.[4][5] Intuitive knowledge tends to be approximate.[6]

Since every temperature system needs an explanation, namely the reference points, no system is or even can be intuitive per this definition.
