So you have no idea what you are talking about. Tradeleves if you are overleveled for them make you very little if anything at all once you tak into account the gil/time you have to spend to acquire the items, the repair costs for making the items and the time required to farm that enough to become profitable. Same the same exact problem exists with your second and third examples as well. You obviously have no idea about endgame if you think any of what you are stating is positive gil flow. I would encourage you to research some more before you make such massively ignorant statements but that probably won't happen.
