I think your point stands, but something feels wrong to me about "you optimize for readability [...] You spread your code over 5 directories, 50 subdirectories, 3000 files."

We need lots of tooling to keep our code readable across a zillion files.

And it is worse than you mention. You rarely get 60 files per directory, and, in addition to the files you want, your package manager and build system add a few zillion of their own that all can break your build in 'interesting' ways.
