The post you reference doesn't mention how the water gets into the car.  Bad door seals?  Holes in the floor?  The problem isn't the jute, it's a leaky Z that allows water to puddle on the floor.  That's a very severe leak that needs to be fixed no matter what material is under the carpet.  As for jute alternatives, you can use house carpet padding, dynamat for heat and sound deadening, and a good coat of paint on your new floor panels.  But, I'm sure you saw those options mentioned when you did a search.  If you're replacing the rubber seals on your Z as part of your restoration, you should have no worries, even in the tropics.
