There are a lotta smart people emailing me saying

Amazon

(AMZN) - Get Report

in the end has to go out of business, that it just doesn't make enough money on what it sells.

I am not long Amazon. But let me give you the big bull case. It's the "Last Man Standing" standing defense, and, from where I sit, Amazon might have it dead right.

It goes like this: Amazon has a war chest. One thing is for certain; the company has had little problem replenishing that war chest. In the meantime it sells many goods at ultra-low prices, betting that it can hook you. I know I am hooked. I buy more books now and go to the library less than any other time in my life.

There were initially many Amazon-esque pretenders with frictionless models out there. They are almost all at their 52-week low. They are pathetic stinking losers. Most of them have no hope and go up only on periodic short squeezes. Most investors feel totally fleeced by the sector. I couldn't bring public a dot-com competitor of Amazon now if I offered a $3 selling concession per share -- and that's huge. I wouldn't buy one of these even if it sold at its cash position, which some of them do.

So what happens next?

Simple: They all go out of business and Amazon takes its hooked populace of eager users and it

raises the price

. It can do that because it is the last man standing!

That's the bull case. Right now it looks so unassailable that I almost bought 25,000! But

Now you know what I know. Good luck with it.
