Why did Napoleon consider the Louisiana Territory a valuable part of his plan to regain control of Saint-Domingue?

With the territory, he could secure military assistance from Spain and the United States to overtake the revolt in Saint-Domingue.
Trade on the Mississippi River within the Louisiana Territory would provide supplies to the French settlers in Saint-Domingue.
The idea of individual rights, which was thriving in the Louisiana Territory, would help Napoleon appeal to the people of Saint-Domingue.
Colonists in the Louisiana Territory, where slavery was legal, might have influence over the people in Saint-Domingue.
