Your argument is hideous. The destruction of wealth seems to mean nothing to you.
A market is comprised of ALL its participants, regardless of who they are, how much trading capital they have, or what motivates their trading decisions. Any theory of market analysis that has any validity must be able to account for actual market action. That means it has to account for the behavior of any and all participants—including governments, central banks, investment banks hedgefunds and evil multibillionaires.
There is a large cohort of traders who are consistently profitable over time, in spite of news events, natural disasters, government intervention and attempts at manipulation. Some of them are billionaires, but most have much smaller amounts of trading capital, and have absolutely no ability (as individuals) to move the market.
Traders can be consistently profitable using precisely the same techniques that professional gamblers use to consistently make money: Money management, risk management, self discipline and trading based on the relative probabilities. Markets are not deterministic, but neither are they random. It is usually possible to determine when the probability is far higher that the market will rise and not fall, or fall and not rise. Just as it is usually possible to determine when you probably have a winning hand, and when you probably don't.
I dunno. I’m thinking we all need to move to sourcery’s land, where driving a company’s capitalization to near zero is a painless affair with no consequences.
Companies just go merrily along doing business as usual. Their creditors don’t get spooked. Their suppliers don’t demand cash. Now that’s the place to do business. Unicorns crap rainbows there, too.
