Well, no, you can't use Bitcoin for integrated circuitry. Since it's literally bits, it's not useful as jewellery either. So let's put that aside. There isn't even a point discussing it. Gold wins here, hands down. Some people do think the addresses, both in b64 and QR form are quite aesthetic tho...
What we are really discussing is the ease and cost of transacting these assets. Ask any South African armed transport guard, and he'll tell you that he'd only transport gold in a heavily armoured truck, with heavy weapons and backup. Despite that, a lot of trucks, with far less value than gold in it, get violently hijacked every year. Sometimes even with RPG's! I can't imagine the cost of all that, but let's just agree that it's extremely expensive. So I think you can safely say that gold is both harder and more expensive to mine, transact and to look after than Bitcoin. Meanwhile all you need to keep your Bitcoin safe is a private key.
Bitcoin has at least 4 highly valuable use cases.
1. It's regulation resistant. When two parties voluntarily agree to exchange Bitcoin for a trade, nobody can step in between.
2. It's crime resistant. It's almost useless for extortions due to how flagged addresses and accounts can be tracked and shut down by users and exchanges.
3. It's easy and painless to transact across borders and regulated regions.
4. It's a store of value, due to how it's an absolutely finite resource.
It beats gold hands down in all these categories. On top of that it's far more environmentally friendly than gold. But no, you can't fill your teeth with it.
