So where are the alternative valuations? Where are the alternative business models that don't emphasise stock ownership and stock value? Where is free public access to the freshest financial data and hyper-speed trading platforms?

Why do you never see anyone arguing that a bank balance is just a bit pattern, and if you copy a bit pattern from one place to another you're not actually stealing anything?

You regularly see this argument from opponents of DRM who are justifying the copying of artistic work. Why do they never apply it to finance?

What gives money a special pass on this?

If you can't answer that question without thinking it through - i.e. without just responding emotionally with an 'OMG the world would end if everyone did that' - then you can't make a statement like 'most modes of unfairness are almost fully compensated for' and expect to get free pass on it either.

>If you're trading a major stock like Apple you can be sure you'll trade for a value near the market's best estimate of what the true long-term value of that stock.

There is no such thing as a market. There are only people, and politics, and political relationships.

Finance and 'markets' are just quantified politics, which - like all political systems - happen to privilege one particular set of actors.

>he can be sure he won't be ripped off and can sell for no more or no less than the value of his goods; he can choose to sell at any time, he'll be able to do so instantly.

If you knew anything about farming you'd know that this is exactly what doesn't happen. What actually happens - in the UK at least - is that buyers form cartels and dictate prices to sellers.

Smarter countries like Canada regulate prices to keep farms working. (Forcing a farm to close because of one bad financial year is dangerously stupid if you want to keep feeding your population.)

But manipulation couldn't happen in the pure world of finance, surely?

But that couldn't happen to stock prices, could it?

The alternative valuations are right there in the market. If "alternative valuations" I were to place an order to purchase 100 shares of apple stock at $10 per share simply because I favor an alternative valuation I could do so but my order will not be filled. This is because the valuation is not correct.

"alternative business models" Publicly traded companies emphasize stock value because it is their duty to do so. The owners of the company have a right to collectively demand this. If the company fails to promote the value of the stock then the owners will sell their stock and the price will adjust to reflect this increase in supply/fall in demand.

"free public access to data/hyper-speed trading platforms" They are publicly available but they are not free. Data is a good, goods cost money. Believe it or not it takes quite a lot of effort to deliver these products.

"bit pattern" What are you talking about? DRM in finance? You aren't making sense here.

"There is no such thing as a market" Yes there is. People buy and sell companies and commodities on various exchanges. These exchanges are called markets.

"buyers form cartels and dictate prices" The market dictates prices. There are market makers who are legally obligated to buy and sell within a certain range of the free market price. This ensures liquidity and it is not some sort of scam.

"manipulation couldn't happen" Your sarcasm is obvious. People commit crimes, it doesn't mean that the whole system is broken. Often they also go to jail for these crimes.

You can call up a bunch of buyers directly if you want. You might even get a better price for your efforts.

> Where are the alternative business models that don't emphasise stock ownership and stock value?

Nonprofits exist. So do corporations with particular requirements in their charter. What exactly are you after?

> Where is free public access to the freshest financial data and hyper-speed trading platforms?

If you want a consolidated feed at the standard 5s latency you can get it on standard terms at a reasonably proportionate price. If you want dedicated fast feeds there are companies who sell them. No-one's giving it away for free and why would they?

> You regularly see this argument from opponents of DRM who are justifying the copying of artistic work. Why do they never apply it to finance?

Because everyone knows the value of money or stock is in its artificial scarcity, whereas the value of art is supposed to be actual value.

Forex is a jungle, in part because there aren't public markets and exchanges the way there are for stocks.

Huh? That's saying that stock prices fall because the companies the stocks were of - ordinary, non-finance companies - had been price-fixing (and can no longer expect to profit from that now that they've been indicted).
