Yes, there are strategies around how to optimally milk the period of price change. I was talking about the equilibrium state here. The point I was making was that even if you cause a price drop by flooding the market, it might not be a bad outcome; you could end up making more profit than was being made by your competitors before you entered the market. To your point, it's true that even if the equilibrium state isn't more profitable for an actor, they would still be incentivized to increase the supply if they could temporarily widen their profit margins while the price is changing (e.g. until the competitors can catch up). But I think that the equilibrium state provides a simpler working example of the general point I was making.
