Either way

Either way you have to take those steps before the meltdown, while the infrastructure still makes bitcoin transactions feasible. You can't convert bitcoins to physical BC (or gold or MREs or anything else) without global internet connectivity, because you can't validate the bitcoins without that.

BTW it's not the power grid that matters. A battery-powered laptop is perfectly fine. It's internet connectivity that you need to validate the bitcoins, and the connectivity has to be world-wide. It doesn't take a global meltdown, either. A war in which internet connectivity via undersea cable and satellite was disrupted would be enough.
