So, it is interesting to know who is behind bitcoin but ...

... why is it important?

I mean, let's say it was not a state guy but some agency, like with the xz utils backdoor (that was most likely not a solo dev, the coordination, time and planning seemed to indicate a state actor; also peculiar to see western-style folks use asian names here). Would that change the situation with regards to bitcoins?

Ultimately what should matter is whether xyz is secure or not. I just don't get the epic fascination with "who is mystery man 101".
