I'm sure that they keep spare guillotines around but I'm not sure that it would be a popular thing to punish random Louis libra user for his few hundres Euro transaction when Facebook is paying less in taxes than him, figuratively speaking.
Sadly it is not uncommon to see people going to jail for stealing a few chicken because they were hungry, while many company owners and politicians hardly face any jail time for their proven corruption affairs.
Stealing a chicken is very different from using something. Stealing chicken is no doubt immoral for most people but punishing the usage of something that Americans can use will not fly unless the USA becomes the arch-enemy and using Libra is perceived as treason and way or unfair enrichment.
Stealing a chicken has a clearly defined victim and stealing, not even piracy or patent infringement is well understood and universally condemned action.
