| I’m not talking about FTP, which isn’t a network file system. I’m talking about NFS, AFS, and sucessors in that line of development. E.g. https://www.slideshare.net/mobile/snehcp/coda-file-system. I’m literally talking about the theory of the paper by Richard Gabriel (https://www.dreamsongs.com/RiseOfWorseIsBetter.html) which is that worse solutions often win because it takes too much time to bring a good solution to market. If you were trying to make a “good” solution to the problem addressed by Drop Box, it probably would not look like Drop Box. For example, you’d do a real network file system that wouldn’t need to do a binary diff of the file each time to see what changed, because it would have access to the block level changes at the file system layer.[1] You'd have file locking in the protocol (like CFS), and could sync data from a locked file instead of waiting for the lock to be released.[1] It also probably wouldn’t have made Houston a billionaire because who is going to install a kernel driver off the internet? But on the flip side, Dropbox almost certainly killed much of the interest in real network file systems, because it is good enough. Which is why we’re all using an internet powered by Javascript, Electron apps on the desktop, etc. Worse is better. [1] https://www.dropbox.com/help/syncing-uploads/upload-entire-f...

NFS and AFS (from what limited I know of it) are more designed for local networks thus to leverage NFS over a WAN you'd then need to tunnel your connection (eg via SSH or VPN). So while there is obviously overlap between them and Dropbox I wouldn't really say the two are all that comparable.
However to answer your point, I don't think anyone would disagree with the specific part of your point regarding how simplicity is often better than something arguably more powerful. However just because something is simple it doesn't mean it isn't also good. "Good" is just a question of whether it meets requirements. If your requirement is that it can be installed and operated by layman then Dropbox is a far better solution than any other the other proposals you've mentioned.
