Would care to elaborate on the reasoning that brought you to this conclusion ?

I think I know why it's not failing right now despite the massive expansion (x5) of the USD "coin supply", but I can't see those conditions sustainable for a long period.

For example, what makes you so confident that the trillions backed up on Fed balance sheets, or the Chinese held $1T in USD bonds or the Japanese held $1T in USD bonds or the huge amounts of dollar denominated sovereign wealth funds held by the Gulf region countries won't find their way back out into the markets ?
