Satoshi also predicted hyperinflation in 2008 after central banks intervened to mitigate the financial crisis. He was most likely a computer scientist, definitely not an economist.

Hal Finney was not Satoshi, and there's not a single shred of evidence in that wiki article pointing towards him. Instead it's just his grieving family being traumatized by scammers.

The evidence is circumstantial but not conclusive.

Did Finney ever explain how he came to be the recipient of the first ever Bitcoin transaction if he wasn't Satoshi?

Who do you think is Satoshi, if not Finney?

There is nothing to explain, it is public knowledge. The transaction you mention happened after the public announcement of bitcoin on a mailing list which Hal Finney was active on, and after Satoshi reached out directly to Hal (and others).

A correct prediction of the former doesn't imply a correct prediction of the latter. For what it's worth, I think it will become stable at around zero USD.
