Point taken about anonymity. However, its design (that of cash) is theoretically anonymous, it is reality which gets in the way. BTC, on the other hand, is "just" a huge ledger of transactions with giver and receiver perfectly "identified" (in a unique way, albeit just pseudonymous) and preserved forever.

Also, as you point out, BTC is a massive waste of resources and storage space.

> giver and receiver perfectly "identified" (in a unique way, albeit just pseudonymous)

Not perfectly. A lot of heuristics are needed to link a unique owner to multiple transactions. With bitcoin, it's recommended to use a new address for every transaction so, for example, in a basic transaction, it's not so easy to identify which output is the recipient and which is the change.

And there's Monero that tries to hide these links a lot more.
