Earlier quoted context omitted.
The first paragraph is a fair consideration. The second is a complete stretch. It's not as if America would suddenly stop providing military support to Saudi Arabia if we suddenly switched to bitcoin. An America that historically used Bitcoin would be even more incentivized to "secure" fossil fuel nations.
If the Saudis started selling oil in bitcoin they'd probably lose their military support and/or be overthrown. It is difficult to justify why the US is providing militarily support to the Saudis without invoking oil and dollars. They are a pretty shady regime and not the sort of people the US wants to be supporting. And the Saudis don't seem to be trading with America as much as China [0, 1]. [0] https://tradingecono…
Reminds me of one of by favourite Frankie Boyle jokes: "Our government was angry about Khashoggi. We sent the Saudis a strongly worded arms invoice."
