the szabo is a better denomination for the public to think about ETH. saying “300 szabo” is easier to understand than saying “0.0003 ETH.”

it is impractical and silly to use a number with lots of decimal places when talking about money. only computer nerds will ever want to do that. the public needs a more friendly unit of account. given that 1 ETH = 10⁶ szabo, and assuming 1 ETH goes for $3300, then a dollar is worth about 303 szabo. this is a lot more friendly and I think the public will like it better.

you can peek over the fence and see what the bitcoin ecosystem is doing. their wallet apps are gradually shifting over to the satoshi as the default and primary denomination. they are starting to say things like "a dollar is worth 1000 satoshi," or "I paid ten thousand sats for that." that's easier to conceptualize and people will like it better in the long run.

the szabo is very practical. it is roughly double the value of the Japanese Yen, and millions of people price things in terms of JPY. so do you want to buy a $20 item for 0.006 ETH or would you rather pay 6,000 szabo?
