What the fuck is the problem with crashing a market? All of these fucking isekai which have pretensions of semi-literate financial knowledge all scream "the market will be destroyed!" but no businessman in their right mind wouldn't be interested in seeing such an unbelievable blockbuster development through. Keeping a separate market afloat because you hide a breakthrough of your own is so stupid, so fundamentally idiotic, that I don't know what could possibly be going through the author's head.
