Bitcoin does NOT have scarcity because it is capped at 21 million.
This is the most hilarious thing ive read from you in a long time. Scarcity means the supply relative to other goods. You cant get more than 21 million Bitcoin no matter how hard you will try, or how many numbers exist. It cant get more scarce than this.
This is like saying that O2 molecules have scarcity because they are put in a container that by that definition can take only limited number of those molecules. In the same way Nakamoto put limited amount of numbers (21 million) in their container and gave them the name bitcoins. That doesn't make these numbers scarce, because numbers are all around us, just like O2 molecules.
This is like thinking land on earth isnt scarce too, because theres trillions of other planets that have land too.
