Keeping in mind the most important factor, without gold and silver, all electronic equipment wouldn't exist = bitcoin would not exist. Computers, phones, tv's, etc ALL require silver and gold to be manufactured.
We don't live in an alternate universe, we live in this one where gold and silver exists and will continue to exist and be used to manufacture electronics. In other words your arguments are moot.
Store of value can only be experienced through long term value stability. Bitcoin is unpredictable, and volatile. If and when it becomes stable (price wise), then and only then does it earn the right to be declared "store of value".
This is why bitcoin was invented as a currency not a store of value. It can and is being used as a medium of exchange and only to some extent it can act as a store of value when you look at it from a long term perspective and ignore the short term volatility.
