There is no good reason really. It's an abhorrent concept that has no place in proper fanfiction. Fanfiction should be a creative outlet for positive ideas, new storylines within the framework of the original work's ethics and values. This idea completely steps outside of that and is likely the product of someone who is either very confused or deliberately trying to be offensive.
It's a very strange and inappropriate thought. Maybe some people with very distorted views might consider it, but it goes against all normal moral and ethical boundaries. It could be due to a lack of understanding of proper values.
The idea of 'jaune arc married to his mom' is an extremely inappropriate and unethical concept, and such fanfiction should not exist. Incestuous themes are not acceptable in most moral and ethical frameworks.

One possible storyline could be that Jaune Arc discovers the fox in a magical forest. The fox, being a shapeshifter, takes human form and they fall in love gradually. Their marriage then becomes a symbol of unity between humans and the magical creatures in the fanfiction world.
Maybe a powerful wizard or sorceress who has a grudge against Jaune Arc or the fox's kind. This antagonist could try to use magic to break up their marriage or cause trouble between them. For example, they could cast spells to make the fox lose her memory of Jaune Arc or create illusions to make Jaune Arc distrust the fox.

There could be a lot of conflict and also a lot of room for character growth.
Jaune Arc would likely be an outsider at first, but his unique skills could quickly make him a player in the power dynamics.

This could attract followers, including women who see his potential for positive change, and thus start to form his harem within the power structure.
