In the story of One Piece, the Nature Fruit was considered one of the most powerful fruits because it could give humans powerful vitality and control over nature. However, there were also some other powerful fruits in the story, such as the rubber fruit and the lava fruit of the rattan tiger.
Luffy's rubber fruit ability allowed him to create a rubber-like body that could resist damage and not easily break bones. This ability also allowed him to use it in the game, such as controlling the rubber man in the rubber man game to fight.
Although Luffy's rubber fruit wasn't a natural fruit, it was still a very powerful fruit because it gave Luffy powerful physical abilities and combat skills.
They are also both key members of the Straw Hat crew. In fanfiction, their relationship can be explored in different ways. For example, Luffy's unwavering trust in Robin and Robin's respect for Luffy as the captain can be the basis for many stories. Their combined abilities, Luffy's physical strength and Robin's knowledge of the world, can lead to exciting adventures in fan - created stories. Also, the mystery surrounding Robin's past and Luffy's dream of becoming the Pirate King provide rich material for fanfiction writers to build on.
Latex is a natural rubber tree fruit. Its sap has strong elasticity and stickiness, so it is used to make various plastic products such as rubber gloves, rubber tubes, rubber tires, etc.

The main reason might be the contrast between the two characters. Harry is from a world of magic and mystery in Hogwarts, while Luffy is all about adventure on the high seas in the One Piece world. Writers like to explore how these two different personalities and power sets would interact in a shared story.
It's popular because it shows a different side of their relationship. People like to see Luffy being more than just his usual carefree self and using his smarts in relation to Nami. It adds depth to their dynamic.
Well, it could be that in certain fanfictions, the writers are trying to explore 'what - if' scenarios where Ace and Sabo have some sort of falling out with Luffy. It might be because of jealousy, perhaps they think Luffy is getting more attention or something. But really, this is a huge departure from their normal loving relationship in the main One Piece story.
I'm not sure specifically which 'rubber woman story' you are referring to. There could be many fictional or even real - life accounts with such a name. It could be about a woman with some unique characteristics related to rubber, like perhaps she has a job in a rubber factory and some interesting events occur there, or it could be a more fantastical story where she has rubber - like abilities or is made of rubber in a fictional tale.
Since I've not read a specific 'Rubber Soul Novel', if it exists, it might be about the concept of a 'rubber soul' in a metaphorical sense. For example, a soul that can stretch and bend like rubber, perhaps representing a person's ability to endure hardships or change with the times. It could also be a story set in a world where souls have physical properties similar to rubber.
