it comes back to trust actually.
nobody would *trust* Bitcoin if the ledger was obfuscated. transparency was necessary for the 1st-mover.
normies have come to *trust* that Bitcoin can't be hacked or created out of thin air. normal, non-technical people now understand nobody can spend from an address that belongs to another. this is because of the cryptographic fundamentals but they aren't auditing the code themselves.
in this same way, people will come to *trust* the cryptographic proofs that Monero uses to guarantee supply and hide sender, receive and amount.
it will become normalized that these systems function correctly, despite not knowing exactly HOW they work.
We all are placing trust at some level and it's important to be realistic about *where and *how that trust is given..
