The dispute on Lothal Planet could not affect the construction of a brand-new secret industrial base here by the Duchy of Dawn.
Moreover, this industrial base was located somewhere the Galactic Empire would find difficult to attend to, because it was simply too remote. In the original storyline, Mon Calamari Planet—Dak Planet—suffered multiple invasions by the Galactic Empire, yet the Imperial army was never able to occupy it for long.
PS: A reminder: Mon Calamari Planet was originally called Dak Planet. Only after the Quarren lost their war against the Mon Calamari, with control of the planet falling into Mon Calamari hands, was it renamed Mon Calamari Planet or Mon Calamari. However, in this story, Tang Xiao supported the Quarren in retaking control of Mon Calamari Planet, so its name was changed back to Dak Planet. The Freedom Dark Volunteer Engineering Corps, established under Quarren leadership, also reflected the Quarren desire to return to the era of Dak Planet.
As the struggle continued, Mon Calamari Planet gradually became one of the Rebel Alliance's most important industrial bases, supplying the movement to rebel against the Empire with large numbers of high-performance warships.
In Tang Xiao's plans, even if Dak Planet came under attack from the Galactic Empire, its remote location would allow him to easily cut off the Galactic Empire fleet's supply lines and slowly grind them to death.
In fact, this was how the Rebel Alliance dealt with the Galactic Empire in the original storyline.
It was not that Tang Xiao had failed to consider Lothal Planet's role as one of the Rebel Alliance's important places of origin. However, he believed that the Rebel Alliance's problem could at least be kept under control on Lothal Planet. Perhaps he could negotiate terms with the Rebel Alliance when the time came.
