Futures Options Margin Buying Futures On Margin And Demanding Delivery?

Buying futures on margin and demanding delivery? - futures options margin

I think I missed something, but if possible, the risk is not only the market risk - this is not a "risk" the thinking on this topic.
What I mean is:

Take long position, while in the performance bond (margin). Take a few minutes, until the expiration date and the cover, so that the elimination of market risks (price volatility). When the contract came to power and his long-term position is open - when the demand for physical delivery of the goods. Obviously, the point is, if you bought at 10:1, for example, its profit margin is more than obvious.
I thought for similar cases in the traditional stocks, CFDs, options, spot, swaps - but between those instruments, "margin" is always a loan, not a deposit of "good faith".
Another thing I noticed that 90% of drivers who do not participate in physical delivery. This means that even if I think it is true, then we have a brokerage in respect of serious (or 500k to pay for membership in CBOT (Nymex) has to find) any + bureaucracy.
Also, I am not sure if the clearING Home I will maintain in cases where the intention of their position to + I do not know whether some tests require ridiculous it is prepared to manage the delivery of secure online payments (eg + Quota).
But honestly, I do not know care for material goods to buy gold / Forward FX contracts will be good. Nevertheless, for 2 years studying economics only what I have learned is that the only purpose of the dealers that need to earn money, regardless of whether the party who loses everything (... a score more fun for the weekend -- although I am 100% serious to say).

Well, I have no intention of keeping the issue open for long if there is a truth ... but ...

Thanks
