On my blog I ask the following:
I’ve heard people [that] argue for limited purpose banking use an example of gas stations. They say that consumers can only really buy and sell petrol from BP, and quite rightly cannot engage in complex futures contracts. But why not?
Imagine that you are considering booking a holiday, but there is a critical issue that will determine whether or not you will be able to go. At the moment the price is cheap, and you do not want to have to wait before making the booking. Why is it the case that I cannot buy an option? For, say, £50 I attain the right to buy the holiday at a specified price, before a specified term?
… why no options on holidays?
