the smallest unit of Bitcoin, could end up being more valuable than entire national currencies. Not theoretically. In real purchasing power.
Wrong. The purchasing power is not decided by how many fiat shitcoins worth 1 sat. That is purely fiat mindset.
The purchasing power of 1 sat is decided by free market, when you buy/sell products and services and use Bitcoin as medium of exchange.
I suggest you to leave away this fiat mindset and read this important article from 2014: https://fee.org/articles/what-gave-bitcoin-its-value/
