Not keeping out of focus or wonky negatives is "throwaway society"??
No, that is good housekeeping!
What I submit is that knowing our digital data is not reasonably accessible for 50-100 years (and digital storage IS less permanent that that) and assuming it does have that longevity is an attitude of 'throw away' value of things, (or being an ostrich on the topic). So destroying our negs because we have digitzed them is a pollyanna view if the permanene of the digital data access.
And while we as hobbyists photographers might have little chance of value of our images after we have passed, other photographers -- like those whose profession is is record/document human events and our surroundings -- suffer from the same problems of digital data permanence...Years of professionally recorded music that were 'archived' to digital have ALREADY been lost!
