Was Satoshi's thinking of a real peer-to-peer cash system allowing micropayments to happen or was he just wanting to make a threat and rebellion for the current scam financial system?
In the original white paper you can found he was aiming to bring to the world a peer-to-peer cash system and you can see also from the following original white paper Satoshi's quote:
While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model.
So since the beginning Satoshi was indeed worried about the trust model the financial system keep from themselves.
In this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.
He was indeed, most worried about the trust issue rather than allowing micropayments with a peer-to-peer cash system. This was understandable because from the beginning nobody couldn't tell if the system proposed were going to be successful or not so was better first to solve the trust issue and mostly because the recent 2008 financial crisis.
Some other Satoshi's quote that suggest the aiming to micropayments:
The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for nonreversible
services.
So in conclusion you can say Satoshi indeed solve the trust issue of a centralized monetary system and although today Bitcoin is the most widely used cryptocurrency that allows wealth transfer in a decentralized way it also lack of the main features purposes that is to accomplish small casual transactions with lower costs.
So in my personal point of view I see Satoshi's first attempt to solve the centralized trust issue with a decentralized ledger called now blockchain but then for micropayments we found it's vulnerabilities and we call them scaling issues. So my hope is, in the 10th anniversary of Bitcoin we can retake his original idea and now with the research and advance of the decentralized systems we can found a better way to accomplish it's main idea.
I know it's just matter of time Bitcoin will solve all it's issues and reach the adoption and awareness it deserves all across the world
