Save for tracking both gold and BTC's price, I think we shouldn't be comparing them that much. They've both been used as currency and that's where the similarities end. One is physical, one exists as 0s and 1s. Both have their uses.
Gold is way better than bitcoin in reality. If we're being practical in such a way where internet is not a good thing anymore, gold is a precious thing. It can be sold for a lot of money in the future while the bitcoin can be replaced by an upgraded or a thing that is way more better and has a lot of benefits.
When people hoard stuff, they usually think of worst case scenarios. You'd find it hard to sell gold in SHTF situations. Only good thing is that no matter how much time passes, your gold cache would still be gold. BTC would not survive the destruction of the internet and power grid.
Agreed with BTC's possibility of obsolescence with newer techs though.
