Why post and pier? Offhand I can offer a couple of reasons: Easy access to all mechanical systems (have you ever tried to move a bath or a toilet in a slab based house?) and more importantly in the tropics for good air flow and cooling. An easy variant of true post and pier would be to construct a poured perimeter foundation, then elevate the structure above it for the above stated reasons. My Cal townhouse is built that way, and it's a joy to be able to do maintenance without having to jackhammer the slab!
