Probably a combination of all of the above. When git won the VCS war, the local repo aspect was very important compared to prior options. It's fast enough, generally, except when using large files like in game dev where people prefer perforce.

Git is very much "good enough" for many people. The number of foot guns and lack of a well trodden path for many centralized corporate devs is quite high, but many people are content with it.

Personally, I think if the only advantage is git formalizes a merkle tree and sha based text comparisons with a poor cli ui, it's not very good. But many people think this is sufficient.
