Except for one, not anymore, and two, the value of gold doesn't only come from speculation like in BTC, but from supply and demand from real world applications of gold, like semiconductors, electronics, aerospace, automotive, medical, etc. since it's one of the best electrical conductors and heat reflecting materials we have.

Without gold, we'd be screwed royally, making the current supply chain disruptions seem like a walk in the park. Without BTC, we could fork 1000 other crypto-coins onto which people can speculate on and nothing would be lost.
