Then you would have to have millions of buttons for the millions of things people do with files. The beauty of the filesystem is that a single function (save) can be extended by other programs into many things. (Source control, file transfer, editing in another program, ect.)

The fact that you don't manually save does not mean the files aren't represented on a file system. Source control, file transfer and editing in another program can work unchanged.

Though you would need to worry about atomicity when having a file open in two editors constantly "auto-saving" the document; you'd need some way to synchronise state. Probably easiest to make file write access exlusive by default.
