I think standby is a totally difference situation. I used to fly military standby when I was on active duty in the Navy. You understood that you would only get a seat (at a greatly reduced price) if there was an available seat after all regular paying customers had boarded. Regular standby is similar, without the discount I would assume.
In my experience there are very few times that ticket costs are refundable, unless it is many days prior to the flight. The bottom line, IMHO, is that the airlines have no problem getting revenue from a no-show and then placing a new paying customer in the same seat. It's kind of "double booking."
Insurance companies have done this kind of double-billing thing for years. They adjust rates so that they are almost assured of making a profit on each individual insured, instead of making a smaller, but still substantial, profit on the entire population of those insured.
The remedy for both airlines and the insurance industry is the development of some good laws to prevent gouging of this sort, sort like usury laws in the banking industry.
