You’re intentionally missing the point. The point is that sats are the small denominations that kids would learn about and use to buy candy. And whether we call that small denomination “sats” or “bitcoin” doesn’t matter and is just as arbitrary and easy to learn as it was to learn about “nickels” and “dimes.” Probably even easier if you ask me.

Sure, my point is that Sats is the only word kids (or anyone else) will learn. There will be no need to learn any other word. This is the same as in countries like Vietnam where you have just one quantum currency unit, and everything is expressed as a value of that. Kids in Vietnam don't learn any other word to express currency besides Dong. Everything is just a number of Dong, a small number or a big number. Sats will be used the way Dong is used in Vietnam—for absolutely everything. The word Bitcoin, will have no classificatory value and will thus fade out of all usage. Just like there is no separate word in Vietnam for 100 million dong. It's just 100 million dong.
Many countries are like this, I'm just using Vietnam as an example. In all countries that have multiple tiered units in use (dollars + cents) this is because the highest unit still has relevance in day to day life. A dollar is something you can price a sandwich in. 100,000 dollars is not, hence we don't have a separate word for 100,000 dollars.
