Incidentally, there has yet to be a public transaction in Bitcoin's history in which people have purchased anything in the real world.
Inaccurate. People use Bitcoin to buy and sell goods and services every day. There isn't any reason for these transactions to be publicized in the media/forums like the Bitcoin pizza transaction because that event was the first time that Bitcoin was traded for something in the real world. Investopedia recognizes use-cases of Bitcoin for goods and services, listing car dealerships, and stores such as jewelers, tech providers, e-commerce and more. It's no longer a question as to whether Bitcoin can be used to buy real-world items or not. It's already established.
