I get both your points of view, you are just both a little too extremist in your opinions. Yes too much perlite in soil is not good, you will lack nutrients for the roots if all they get is water. Yes you can grow huge plants with just perlite and hydroponic nutes. Never in nature has a plant requiring as much oxygen to it's root base grown directly in water.(correct me if I'm wrong)
I find the best combination is 50% CANNA coco(50L for 20$) and 50% perlite(if anything, I put a little less perlite than coco) then Canna A & B(30$) nutrients. Cheap, simple,
can't over water, same price as good soil and and what you would buy to put in it. Great results if you give them the light and ventilation they need.
Plus you can reuse your coco, just cut out the root ball, flush well(untill run off ppm is under 300 at least). Let dry, empty the coco out of the pot, break it up, work some dolomite lime into it and reuse.
