gulliver turn out be expensive but useful guest for the lillipution explain how?

Gulliver ate a lot for the little Lilliputions to feed him. In fact everything that Gulliver needed became expensive because of his sheer size. His clothes, living quarters and everything else took a great amount of work and resources. Gulliver was also useful because of his size. He could do things that took years for Lilliputians to accomplish. He also was a wonderful weapon to rattle against an enemy.
