Current money market funds at Fidelity or Vanguard have interest rates close to T-bills, it's a good alternative.

Hmmm, not in this context. Arguably all the same risks, and more besides. (counterparty, fraud, financial-systemic, etc)
Besides, I'm not sure non-US-persons can put money into them these days? Maybe so, but investments in US mutual funds are prohibited, for example.
