I agree with what you've said. I would however include a blurb about stock and magazines. That too has changed similarly and today, you can get from Getty, an image for a buck or two which once cost $300-500!
I have crossed over into the new age. I have done many jobs where I sell my services and NOT the prints. I would sell the prints to but that usually is not part of the deal.
For example I did a corporate job (relatively small business) where I just hired out at $150 per hour and at the end of the contract, I handed over all the images - NO post processing, no manipulation just DVD's with 2000 jpg's.
I made about $2500 bucks on that job it's in the bank, and I dont ever have to deal with the images or headaches associated with copyrights. Staff photographers have been doing this for years - just look at National Geographic. They show credits, but a staffer until lately, gets a salary and expenses, and does not get the rights to the images - they do now get some royalties, but that's a recent charge.
Anyhow, I figure out a way to deliver for my clients. I try not to let them think to much about it, and on a project like the one I described, I could try to get greedy and make a ton of the images and their usage, but then I’d have to do all the processing, and keep track of the business and my shots. . . neither things I want to do!
In this case it worked, in yours it may not.
BTW, never has the artist been the one to enforce through suit copyright, sure there's a few cases here and there, but the big players are the MOSTER media mogals like Turner, and Murdoch. They are the one's that always, in the past have held in check our rights - including the rights to free speach and today, they are letting us down. Youre right, we dont have the power, but then again, nothing worth doing has ever been easy. . .
