What would the assets generate revenue based on? If it‘s fiat currencies you still have exposure, if it‘s Libra you run the risk of currency panic and it‘s not dissimilar to a fiat currency panic except there‘s nothing really available to stop precipitous economic effects.
Gov bonds, corporate bonds, REITs, that today all pay USD, or Yen, or Euros, or what have you. So still based on fiat. Except this revenue basket just looks like an opaque, complex security, and we saw how well that turned out during the last financial crisis.
