My argument is more - there will be a time in the future (probably in my lifetime) where there are no modern computers that can read jpeg - much less the multitude of raw formats so many people seem to want to store their images in. We've seen it with obsolete video tape formats, and other media too. The only real preservation method with digital is to keep it in either online storage, and then reformat it to whatever the current is - or transform it back to analog and store that.
