Bitcoin Standard is only going to stay an imaginary scenario, or so I believe. I really, really doubt there will ever be a Bitcoin Standard any where in the World.
Bitcoin has good adoption growth rate so far, it's very impressive and more people became Bitcoiners, Bitcoin maximalists or simply Bitcoin users. It's good and impressive but it is far from Bitcoin Standard that needs to be adopted legally by governments at nearly whole of the world. This condition is very big and hard to achieve so Bitcoin Standard is something hardly achievable too.
Simply because even Gold is easier to manipulate than Bitcoin is. Bitcoin is Transparent, keep this in mind. Most of the World is corrupt. They would never agree to backing up their own Coin in a Transparent Currency. In fact, I do not even know if it is possible in fact to have it as a Standard at all. Seems much more complicated than having Gold was.
I agree with you that governments globally know very well that they have many things to hide against their citizens and benefits of citizens as well. Bitcoin provides something different, transparent, traceable and beneficial so that governments will try as best as possible to prevent citizen's exposure and access to Bitcoin as much as possible.
They know, after 15 years since 2009, that if citizens exposed, used and fell in love with Bitcoin, they will not separate from Bitcoin. So they want to proactively take action, build as many barriers as possible to delay and reduce adoption growth of Bitcoin at their nation and at global scale.
