...why would I want to accept Bitcoin in that case? Pretty sure I am going to want either some other country's currency -- because I still need to buy imported food or fuel or whatever -- or things have gotten so bad that I no longer hand reliable enough Internet service to make use of Bitcoin.

Because Bitcoin has not experienced the same inflation as USD? I'm not sure what point you're trying to argue honestly.

Explain why, just saying you want Euros or something isn't a very convincing argument. Importing cash Euros is non trivial, and good luck finding banks and credit cards that let you transact in them.
