It's not the ships themselves that resemble the problem, but more the turning inward and closing off from the world that really fucked them over. It's why the Europeans could dominate them later on.

The problem is that the log is way shorter than a regular tree, so it falls a lot quicker. With a full-grown tree they have a lot more time to react. With a real tree the collapse would also start much earlier (when half of it is removed) while in the OP webm almost 95% of the log had to be gnawed away before it finally collapses.
