Nakamoto didn't invent blockchains; Merkle did, in 1979. Nakamoto's paper presented a cryptographic scheme which could be used with a choice of blockchain. There are several non-cryptocurrency systems built around synchronizing blockchains, like git. However, Nakamoto was clearly an anarcho-libertarian trying to escape government currency controls, as the first line of the paper makes clear:

A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution.

Not knowing those two things about the Bitcoin paper is why you're getting downvoted. Nakamoto wasn't some random innocent researcher.
