The Lapita Polynesians and other groups in the Pacific faced several challenges that hindered the development of an empire. Geographic isolation, due to the vast distances between islands, limited communication and unified governance. Additionally, the region's diverse environments and resources led to distinct cultural identities, making centralized control difficult. The reliance on navigation and seafaring for trade and subsistence also prioritized mobility over sedentary state-building.
More evidence is surfacing to suggest that the lapita people were a different race than the Polynesians, infact there is little to suggest they were the polynesians ancestors. So they couldn't have created an empire, the lapita were around at a different time than the Polynesians.
The vast expanse of ocean prevented an empire from forming.
The battle at Tours, France led by Charlemagne (I think it was Charlemagne) prevented Islamic expansion.
The Ottoman Empire's military defeats in the Second Siege of Vienna and the naval Battle of Lepanto prevented further Ottoman expansion.
The Romans profited from their empire through developing thriving trading networks and through taxation.

The La Pita Polynesians and other groups in the region faced significant geographical and environmental challenges that hindered the development of an empire. The vast oceanic distances between islands limited trade and communication, making centralized governance difficult. Additionally, the lack of abundant resources and the smaller population sizes compared to continental societies restricted their capacity for large-scale political organization and military conquest. These factors combined to create a decentralized society focused on local subsistence rather than expansive imperial ambitions.

The Byzantine Empire and the Kingdom of France jointly prevented the Muslims from overrunning the European side of the Mediterranean.

The main reason the Hausa did not develop a large empire was due to their fragmented political structure. The region consisted of several city-states that were often in conflict with each other, which hindered the ability to unify and expand into a single empire. Additionally, external factors such as the Fulani jihad in the 19th century further prevented the establishment of a Hausa empire.
It could be argued that the Roman Empire has never fallen because its influence still remains with us even today.
The demise was occasioned by the influx of the peoples of Eurasia - Goths, Vandals, Franks Bulgars etc etc. This massive move of peoples could not be prevented.
