All good reasons to carry olive oil. Here's some other points to think about: Apparently, tapioca maltodextrin is incredibly light (I'm not certain, but I believe 1 lb of the powder comes in a 1 1/2 gallon size plastic ice cream-type tub). It also dissolves instantly on contact with an aqueous substance (therefore returning back to just olive oil). So with a teeny bit of water, you'd have your liquid olive oil again. Would be interesting to find out, from a sheer weight perspective, if the powdered version is the same as simple liquid olive oil. Maybe you'd be trading the worry of leaking bottles/oily messes for the worry of what happens if even the smallest amount of water gets into your powder.
