You certainly could store film cheaply, but you can store it expensively too.

I agree with the permanence of film, and its staying power, but I think the costs being given here are only a select example, and on that favors our side of the table at that.
I'd agree that film storage would, in practice, attract extra costs for monitoring, security, temperature, etc., as you suggest, to make the best of the permanence.

But, surely, digital media would attract similar costs, even ignoring the lack of permanance (what's the life of a CD or a hard drive?) and the obsolescence of the media.

The business where I worked 15 years ago used Zip Drives for data storage...the present boss told me recently that they now have no means of reading the disks. Fortunately the records are obsolete and no longer needed, otherwise it would have been a major and expensive task to bring it forward onto more modern media.
