Had Satoshi named it differently, Bitcoin would probably still be enjoying the success it has today, provided it won't be given too nuisance a name as BoobCoin or BeiberCoin. Bitcoin got its success from its features.

Anyway, how could you even "never go back to the society built by centralized legal tender" when you are living in it?

Finally, Bitcoin is only successful because it is beneficial for human use. It was meant to be a tool for humans to make use of. Other than that, it couldn't have been created even.
