Commercial-grade unix is intended for companies to use for their critical business functions, not for hobbyists or home users. That is the context you need to be thinking of when you see those prices.

For example, at one of my previous jobs we ran a database for one of our clients. That database had details on over 10 million of their customers and hundreds of millions of rows of data. The needed access to it almost 24/7 with 100% uptime except for scheduled outages. It ran on a half-million dollar server and had terabytes of expensive EMC disk arrays behind it. Paying thousands of dollars for a stable, secure, high-availablity OS is not even an issue in a situation like that. The cost of the OS is a drop in the bucket compared to the hardware, software licensing (oracle in this case) and penalties we would have had to pay for not meeting service level agreements due to outages.
