The true value of 1BTC in fiat is infinite. 10BTC is also infinite, 0.5BTC infinite, 0.1BTC infinite. It's math.

On that note, I think some things will eventually become so cheap (free, in some cases), that we will only need to transact in sats for more "valuable" items.
This is the real way of looking at it. We're not earning fiat we're destroying fiat.
