Derivatives let you trade things other than price and are important in hedging against certain types of risk. I don’t think the point is to invest in them so I agree it seems like gambling for most people.
Why is it bonkers though? In a complete free market, everybody does whatever they want and as a result you get the best deal on your insurance premium.
Not inherently, when the numbers get big - strange things happen. It's not unreasonable that there would be insurance of insurance - it's also not unreasonable that there would be market traded contracts for the insurance of insurance. Provided that all parties can maintain their obligations under the contract... which may be a dubious/untested claim.
They're a lot cheaper than buying the actual stock, because there's every chance they'll expire worthless- and when you're hedging, you think they will probably expire worthless, too.
A "person" can't sell a naked option, this can only be done by bigger companies with a margin account, and will be margin-called when the price approaches the strike price.
The point is, should call options used for hedging regulated as insurance?
Margin accounts aren't that exclusive. I opened a margin account just because but I've never dipped into it. It's just a tool and if you know how to use it, good for you.
