Why do we need account abstraction?

Interactions are complicated, require strong key management, & different types of accounts make this a series of logistical hurdles to overcome. But when we interact with the classic web, we typically don't pop open a terminal, fire up openssl and connect with a client-side cert.

i think that kind of protocol(s) maturity has about 50 years into the future.

Why do we need opt-in privacy?

Interactions on most L1s involve a public ledger – the separation of users from a network has many layers of de-anonymization:
- the indexer apis your wallet relies on
- the RPC that received your transaction
- the transaction record itself which shows your address
