The thing is that, many Japanese given names (Satoshi here) are constructed to be meaningful in a positive way anyway. Nakamoto is a well-known surname that is at least several centuries old and thought to mean some central land, though its ultimate origin is unclear (one theory is that it comes from important [or "central"] members of Murakami pirates [1]). Of course Satoshi Nakamoto is clearly a pseudonym so it may have been picked according to literal or even mistook meanings, but it may equally have been picked randomly too.
My pet theory is that Satoshi is actually named after the main character from Pokemon[1]. Which is also the name of the creator of pokemon[2]. And the creator created Bitcoin and other derivatives with the game theory he came up with and refined in the Pokemon series. (Addictive,'gotta catch em all' shitcoins)
If you want another crackpot theory.... there's an anime called "Magical Shopping Arcade Abenobashi" where the main character, named Satoshi, must (if I understand the plot summaries) save the multiverse by saving a shopping mall that exists across multiple timelines.
