I wouldn't call Bitcoin a commodity, commodities are meant to be consumable, and Bitcoin is obviously not. Collectibles are valuable because of their extreme rarity, and Bitcoin is not that rare - up to 21 million coins, and 100 million times more satoshis. I don't think that Bitcoin is all that different from fiat money - they are both valuable because people believe in their value, while inherently they have no uses beyond monetary. The key difference is that fiat's supply is created in a centralized way, and now with the shift towards digital payments, the payments are also processed in a centralized way too.
Satoshi was right, we can assume bitcoin as a collectible or commodity if we compare it with stocks that have dividends.
The commodity isn't always meant to be consumable, you can't consume gold but it is a commodity, commodity is a useful or valuable thing. In economics, a commodity is an economic good that has full or substantial fungibility; that is, the market treats instances of the good as equivalent or nearly so with no regard to who produced them. The price of a commodity good is typically determined as a function of its market as a whole.
