Make Libra a pure money backed by the optimum allocation of liquidity

US Lawmakers Want to Brand Libra a Security, Association Disagrees

A couple of United States lawmakers are looking to classify stablecoins as securities. With Libra considering adopting fiat-pegged stablecoins rather than a single token supported by a basket of national currencies, the proposed crypto project might be facing yet another regulatory hurdle.
Meanwhile, lawmakers sponsoring the bill say stablecoins should be classified as securities to protect U.S. consumers. If passed, stablecoin projects like Libra will potentially fall under the purview of stringent U.S. securities regulations.
Critics of the move remark that such measures only serve to further dampen the country’s position in the emerging digital landscape. Some commentators have long accusedregulators of chilling innovation in the U.S. crypto and blockchain space.
Libra maintains that its proposed stablecoin project is a commodity. The association is also moving forward with developing the payment system, recently releasing updates on the state of its testnet and detailing the number of transactions carried out so far.

If a bunch of US politicians don't like it, move the servers to the Swiss Alps.   Libra, backed by S/L servers have a unique property, all the history is embedded in the accumulated market risk, which is bound.  As such, there is no need for an infinite block chain  simple FX trading pit works fine.

The association can still offer exchange traded securities, no problem.  Merchants get quick transaction times of nearly zero cost and earn interest on remits.  Works great, eliminates the central bank function, bypasses our ignorant economist string pushers completely.
