I'd dispute this conclusion.
If you take a map and draw a circle with the radius of 2500 nm centered in Kuala Lumpur, at least a third of the circle would be comparable to the current search area in terms of inaccessibility. One could even ditch it in the Mariana Trench (and good luck retrieving the wreckage from the depth of 36,000'...)
Inaccessible areas don't have to be in the ocean, either:
