Yeah I'm still using WoS and I think that's impacting zaps, but Au zaps should still work.
I'm what some would call a 'prepper', always have been. The gold/silver thing I think has had its day, how many people today would know how to tell if it's real? Or would trust it? I don't think many at all. Barter, tools, skills, experience, that's all useful in an emergency situation. People would accept tobacco, alcohol, medicines over gold or silver.
