Sorry, can't help as it seems you don't understand margin.
Lol, you believe in fairytales and seem to think margin is created out of thin air ...

No, the broker provides zero! It's just a book value. That's the whole trick in this.As i have said again and again, when trading for a broker with 4:1 margin, you only need to have the margin requirement since the broker is providing the rest of the capital as a loan ...
If you have 1000$, 4:1 margin and you purchase $4000 of stock, you put up your own $1000 deposit and you are $3000 in debt to your broker. You provide $1000, the broker provides $3000. You provide 25%, the broker 75%.
Who is going to give you that loan if you are your own broker ...

But we are talking of the brokerage firm itself! And not of its client!...It seems like you don't understand margin ...
Literally the first sentence on investopedia:
What is Margin?
Margin is the money borrowed from a brokerage firm to purchase an investment.
But we are talking of the brokerage firm itself!...
Man, I already gave you a good example here:If you as your own broker want to trade with leverage you still need to borrow money, just as Lehman did.
Just give us an example on how you think this would work.

I can give you even a better example. Will try to find it...
Got it, finally?Assume, you have EUR 120,000. You could buy shares with that or enter into ten DAX futures positions, for which you would have to pledge a margin of EUR 12,000 (Margin requirement for this example) per contract. The ten contracts, however, would correspond to a DAX equity portfolio of EUR 1,575,000 (10 x DAX-Future contract price 6,000 x EUR 25 index multiplier)

Here, try this example for a bank or broker:
