i like physical silver and gold
but its hard to use thats why fiat was invented
its hard to send physical silver and gold around the world
the world is very global now with plane travel, internet, phone calls etc
we do business/trade with global participants, so silver and gold will never be the commonly used currency again like in roman times
bitcoin is the new and improved fiat 2.0
If one day,after natural disaster,the electricity shut down,bitcoin will be out of function.Maybe physical bitcoins will be usefull.And gold and silver again.
