I think Hearn knows all this already. I'm very skeptical of Bitcoin also and I have heard all these arguments many times.
A couple of points:
- If Bitcoin can't scale on-chain, it's not real P2P currency. So far we don't have any good solutions for scaling Bitcoin.
- Gold is more decentralized than Bitcoin. It can be held and used by anyone without relying on computers and internet access.
