You've created a straw man. No one can make code magically not depend on other code if it does - it's a tautology. No one can argue for better organisation if it's not wanted - feel free to not use a ticket system, don't communicate work, don't rebase work that is interconnected, and don't use logical, atomic commits. I'm not sure that Git is going to be a help given those requirements.

As I've already pointed out, I'm not sure what you're arguing against but it's none of the points made in this thread.
