Sure, the only thing you get is "don't trust, verify that this is truly yours". If you dig deep enough (ecdsa, hash functions etc..) it actually becomes quite difficult to verify, so we are no free of axioms 🤣

It does not, it just picked the only real world thing we had a pre-existing consensus on, namely time, which mitigates the oracle problem. We get away with it, but as such it still exists.
