I can’t figure why Bitcoin would retain it’s value if the dollar collapses—— what would any vendor do with a Bitcoin after collapse? What would be the value of the the Bitcoin? Who would exchange it, and for what?

Do you imagine every other currency in the world will vanish if the dollar collapses? I've bought dozens of things with bitcoin. If/when the dollar collapses then you just buy everything with bitcoin, or anything else that holds value.

The value of bitcoin is in no way dependent on the US dollar.
