For example the price of crude oil fluctuates. Corn, gas, electricity. Every commodity.

If mobile data becomes more of a commodity, it, too, will have a free-floating price.

This guy is claiming his coin isn't regulated because it is a utility to exchange for a product (that doesn't even exist, and may never exist). The rest of that stuff you mention may fluctuate in price, but its a direct price to the end consumer for the product, not a fluctuating price of a "token" to exchange for those products before they exist, but if that is what you are talking about, buying/selling "things" you can exchange for corn before the corn exists that sounds an awful lot like buying/selling futures contracts which is heavily regulated. Either way you would need to find an example that actually fits the facts.
