It seems like based on my research that Hal Finney isn't satoshi. Or at least that Hal made very specific efforts to make it seem like someone else was satoshi and left no fingerprints of his own.
Here's a little of the early work of satoshi whoever he is:
"Total circulation will be 21,000,000 coins. It'll be distributed
to network nodes when they make blocks, with the amount cut in half
every 4 years.
first 4 years: 10,500,000 coins
next 4 years: 5,250,000 coins
next 4 years: 2,625,000 coins
next 4 years: 1,312,500 coins
etc...
When that runs out, the system can support transaction fees if
needed. It's based on open market competition, and there will
probably always be nodes willing to process transactions for free."

gosh I was going to post this 4 hours ago but I got so far down the rabbit hole that I can't remember what I was doing.
maybe another update will come soon. Lots of messages between Hal and Satoshi.
