Honestly, Kirk leaving them on that planet is...not as humane as it looks, unless the Enterprise suddenly is just toting colonization material with them. While they can synthesize stuff (Kirk tells one of those wizards in Catspaw they can manufacture jewels extensively, though this could just be an attribute of the federation writ large than the Constitution-Class ships).
The Reliant coming around on orders from like, Colonial Command to get them out of there and bring them to another world, or bringing more supplies to make a 'proper' colony, and then getting Hijacked, would make a lot more sense.
