In git, everyone has its own repository and its own commit history that can be totally different from each others. In cryptocurrencies, there is one authoritative version that is distributed.
Both are distributed, but git is more decentralized as the central law needs not be pushed to the outer citizens.
You are comparing apples to oranges. Git can be use alone whereas the utility of a cryptocurrency is in the network. You don't say that a video game is "decentralized" because you can play offline do you?
Conversational foul! It was your comparison in the first place. You don't get to accuse someone else of comparing apples and oranges when they describe where you were wrong.

To the degree that's true, it's why we can't expect cryptocurrency implementations to reach git's levels of decentralization. It doesn't somehow make it extra decentralized.
It's not even quite true that the value is in the network - the value is in my ability to safely transact. There have been proposals for digital currencies that allow offline transactions while maintaining resistance to double spends.

No, but only because we don't really have reason to think about them in those terms.
