Yes it does seem like bitcoin is lacking in a few places. You could (try to) add things like * disconnected operation (solve the double spend problem in a disconnected setting) (this would really make something gold-equivalent) * a provably correct, but cryptographically secure ledger (meaning real anonymity) * proof of work based on a single crypto standard seems risky. Use 5 of them. * provably no way to compromise the network even with overwhelming computational power
