Test the top-rated thousand boxers a dozen times a year and it's less than twenty million a year. Pay for it by billing each individual promotion on a sliding scale depending on how much the promotion makes in revenue (obviously Pac Marquez 4 pays a huge slice compared to some non-TV event that features some of the top thousand boxers) and it would work out as a really small promotional expense.
Who's going to agree to cough up millions like that?

Also, what's to stop a fighter from simply refusing to take random drug tests?
