The only problem with case B that I see from the point of view of the elites is that if they choose to invest in crypto and this takes off, they are still powerful but there is going to be a big difference, they do not make the rules anymore, they will no longer have the politic power to affect outcomes like the power they wield right now, right now they can print all the money they want and receive all kind of benefits but with bitcoin this is not going to be the case, so I still think case A is their preferred option.
I imagine this is a pretty widespread point of view. In these things you never know for sure (plus the elites may go down one road and change their mind later, or more likely position themselves for multiple options down the road,) but at this point, watching the news unfold, I would say case B is looking more likely than case A. (Or, at least, the elites are positioning themselves so they can take case B if necessary.)
When I have time I'll post the series of recent news items that support this view -- I suspect most Bitcoiners miss these hidden currents.
The bigger picture is that the last 40+ years of totally fiat money has been the most financially unstable period of modern history, with the possible exception of the interwar period that included the Great Depression. We can expect the elites and their economists to bad-mouth gold, for obvious reasons, but the fact remains that they never gave up any gold or silver standard until they were about to run out of the precious metal.
More generally, the global imperial system that operated since the 1600s has never shoved its power down the throat of the world totally by force. (This goes to the core 'design' of the system.) It always uses a combination of soft and hard power, where neither power is enough by itself, but the combination is enough for the global elites to dominate the world.
A good part of the soft power is the perception that the global imperial power is the most 'liberal' of all states -- meaning it has the most respect for free markets and other 'libertarian' institutions.
Since the global empire has grown used to having both soft and hard power, it has come to rely on soft power and doesn't have enough hard power. (Also, in today's world, it's questionable if hard power alone will ever be enough.) To ally itself with a state-free system like Bitcoin will represent a big boost to soft power.
