Are physical funds PSLV, PHYS, CEF, etc, good for when the SHTF? Will they reset to a fair value?

Just wondering...that's been my plan...play around with AGQ, ZSL, make some money...and switch it over to CEF or one of the Sprott funds. Then...my thinking is...when everything get's "revalued" after a dollar default or an Americo is created...I get the "gold value" of whatever the new currency is. Does this sound like a sound plan? I do have some physical...but buying $100,000 worth seems extreme and VERY illiquid to me. After all, it will eventually have to be exchanged for the new currency anyway...with a premium. This assumes of course that it's not a Mad Max scenario...just an "orderly" monetary reset/depression where I'd eventually buy dividend stocks and get on with life again.

Thanks for your thoughts...
