You sure have a weird way of putting some of these points.
Scarcity leads to value.
Not entirely correct. There are loads of altcoins with capped supply like bitcoin, some even have less max supply than bitcoin but they do not have any value.
In other words scarcity itself does not "lead to value", the utility is the only reason why something has value. Scarcity decides the level of that value.
Decentralization also means that anybody in any nation, except for China at this time, can purchase Bitcoin, utilize BTC, and store Bitcoin with specific, anonymous, keys.
Why are you excluding China?!
But it does because BTC investors, and the nation of El Salvador, has decided it does.
Bitcoin has intrinsic value because it offers a valuable and unique utility as the only working decentralized money in existence. Not because someone else or some country says it does.
Nobody wants anyone looking into their finances. Your finances are your business. Bitcoin is anonymous, meaning although Coinbase might know who you are, they don’t know why you made the transaction.
What does Coinbase, a centralized exchange and a custodial wallet have to do anything with bitcoin's anonymity?!! I hope you know that people shouldn't even be using custodial wallets to store their coins...
