I'm only a hobbyist photog and the bday parties and weddings I've shot result in thousands of images. I can't imagine having to shoot multiple events every week for years. For a pro, the edits represent thousands of hours of work. That the work can be redone theoretically might mean very little to a working photographer.
This is exactly the issue I had in mind, well said.
Raw images seem to be very important until the very moment they’ve been edited (or, hell, rejected from editing). Then their worth is very little.
Raw files, and sidecars, retain their value because sometimes one wishes to revisit an image/edit. If I had to pick one or the other, I might prefer to lose the edited images. That is because I believe I have more/better days of my editing life ahead of me and because I underestimate how much editing I have done. Moreover, there are plenty of RAW images awaiting the day they come to life.
In commercial work, like weddings, the final product is the edit. If there is one thing that must be retained, that is it.
In one case you've lost original sensor information, in the other case you've lost some parameters and possibly the algorithm used. The former is infinitely more difficult to synthesize from scratch.
