As far as I can see it was because more colonists = more population = more taxes.
More colonist would result in increasing population and more taxes.
The Spanish welcomed French-speaking exiles as new colonists for Louisiana because they saw them as potential allies against the British, who were their common enemy. Additionally, the French exiles could help strengthen Spain's presence in the region and contribute to the development of the colony.
The Acadian exiles, French speakers removed by the British from their homes in what is now Canada after the British conquest of New France, were deposited at several locations along the Atlantic and Gulf coasts. Many of them made their way to Louisiana and were accepted there, in part, because the territory was part of the French Empire and they were French.

Frontier colonists.
Following the exile of Acadians to Louisiana, Spain and France enjoyed a good relationship. In addition to a friendly relationship, they both shared the same faith, Catholicism. Many of the Acadians were willing to swear an oath of allegiance to Spain.
Napoleon was willing to sell Louisiana in order to collect money for the impending War against Great Britain, which broke then out on May 15,1803.
