Concerning your title, there is no need to make it dramatic. You've probably read some false opinions crypto twitter have adopted about hyperinflation without even looking at the meaning of the term, or without caring to compare the dollar with the currencies that have hyperinflated. There is no potential collapse for the dollar. Its price is depreciating at the same rate as before, nothing can change unless some major catastrophe hits it. The national currencies that might face problems are the ones of weaker economies. I don't see the rubble facing problems either to be fair with or without sanctions.

By the way thanks for both links. They do contain a lot of useful information, even though I don't usually trust RT, still, this was a useful report. I don't have much to say about gold. A government can ban the possession of a tangible asset, but they won't produce the same effectiveness if they try to ban Bitcoin. I don't hold gold this high as others do, and don't find this asset better than holding cash for limited periods that contain high uncertainty. With cash it is easier to seize opportunities during an economic downturn.
