Honestly, this is exactly what needs to happen as early as is possible.
Of course, the problem is that no one knows when or if this will be possible. While FB has talked about being able to build your own wallets and interoperable applications, there has pointedly been absolutely no discussion of whether Libra will be able to be exchanged outside of the FB architecture.
As someone else noted, Libra at this point resembles World of Warcraft gold more than it resembles what most of us think of as crypto-commodities. That is not an accident.
