do you see how easy that was? Simple arithmetic. Now compare that to the logic required to attempt to verify Monero:
transaction.verify_pedersen_commitments():
transaction.verify_bulletproofs():
transaction.verify_ring_signatures():
have a look in the Monero python cryptography libraries for those functions. So much for simple arithmetic. They are vastly complex, certainly beyond my ability to understand. Maybe you're a better software engineer and cryptographer than me.
So your argument that "Monero can be audited too" is just simply invalid. It's not the same, apples and oranges.
