Are you sure about this? I've heard the quote applied specifically in the context of RAII, where he complained that there is no such thing as a generalized "resource", and that the same mechanism for handling memory access should not be used for file handles and texture maps. I don't have a link right now, but I'm pretty sure it was in his first "ideas for a programming language for games" video back in 2014. Seems to me like this range situation would be fairly analogous to that.
