It’s sad that physical media gets harder to find as time passes. Even collector items can only last so long.

Someone should really fund a sort of (inter-)national library dedicated to preserving physical media - that way, at some point, any company could decide what to remaster.
Or even private people could try their hand at it, as long as the originals remain in the library - the least that could be done would be “scanning/ripping” them and then make the files available for purchase/download.

Anyway, you have a very valid point.
