Some really interesting perspectives here.
Part of what I see dividing people's opinions is whether BTC is perceived as a store or a value or currency. As a currency I definitely think pricing in sats makes more sense than a chocolate bar being priced as a tiny fraction of a bitcoin.
To those that say surely people don't think 1 btc is the smallest value, I can assure you that they do. I actually hazard a guess that if 1 BTC gets to $1million (hopefully it will!) and you randomly stopped people in the street and ask people how much money you need to buy "some" bitcoin, they say you'd need to be a millionaire. I think we crypto bro's often forget how alien this all still is to the masses.
