Factorio is artificially limited to make it more interesting. Real visual programming languages allow building and collapsing abstractions and don't add space constraints. You could just as easily say "text coding is so hard because if I realize I missed a character I have to start the entire file again; it would be nice if I were using something other than 'cat > file.c <<EOF', like visual blocks that could be rearranged later.
