This is true, but for it to stick bitcoin needs to be way less volatile than it is now. Round numbers are useful for pricing and if bitcoin is to become more popular as a currency, smaller denominations have to be used more often. But if volatility is still a major issue, this cannot happen, imagine if the stores have to constantly change that from 100 sats to 104 and then to 97 within one day, this will discourage many from adopting it.

Only other solution is for bitcoin to be valued for goods directly and not as a pair of another currency. So the way you think of value of products in USD, you do the same in BTC, without first converting the value to fiat.
