Hmm... hopefully a good chunk of players sometime in the next month or so drop out of the crafting market. Right now the economic ratio crafting to buying already crafted items is doubtlessly negative for the crafter if they plan on fueling techniques with fragments on the market. The real culprit is the way the crafting system makes much more supply than demand by requiring crafters to go stepwise through a chain of crafting the same crafts over and over again. The result is that we have crafted techniques going for less than 10k, sometimes even close to the 1k minimum, while the absolute minimum in meseta to do a craft from market pricing is more than 200,000. The only way this changes is if either crafters gain access to really easy technique fragments, or people drop out in droves.
You know what would be an interesting calculation though: matching the cost of certain triggers to their hypothetical meseta price through Excube exchange into tech fragments. Say you get on average 30 10* weapons in the highest difficulty on a trigger (probably an overestimation on everything besides perhaps PD). Divide by two for 15 fragments, multiply by 40k earnings per fragment, and you get what, 600,000 meseta base from that UQ, plus whatever value the 12*+ you get are.
