Bhagavad Gita, Chapter 18, Verse 8

He who from fear of bodily trouble relinquishes action, because it is painful, thus performing a Râjasika relinquishment, he obtains not the fruit thereof.

Avoiding real discomfort is named here as the actual motive behind this kind of renunciation, not spiritual insight.

Krishna is specific about what's really driving this choice, physical or emotional difficulty, not genuine detachment. Real motive, once again, decides which mode something belongs to.
