The main arguments is opportunity cost. Every dollar spent (or lost) on that goal is a dollar taken from some other goal. The "standard arguments" are correct though. Your vote absolutely is irrelevant. And this is a thousand times more true in markets where people can make large sums of money by defecting. And if you get past that, the stock price doesn't even affect the company. It's extraordinarily indirect. If you somehow make the stock price artificially low, that will somehow discourage future investors from investing in something similar? It seems unlikely.
