Anyone who claims to require rapid money will not have time to focus on bitcoin because their mind is preoccupied with fast money, which usually leads to failure. All governments that have not accepted bitcoin do not want their currency to lose value, and the main reason is that they cannot control it, so they will not approve it in their country, which I like because if the government has access to bitcoin and control over it, I do not believe bitcoin will be able to move as smoothly as before.
It's technically not possible for a government to be able to have control over Bitcoin or its network and related stuff, all they can do is maybe put regulations on their people for using Bitcoin which is a completely different thing, and that, in no way, is going to stop Bitcoin or disrupt its operations.
The fact that governments can't control Bitcoin and the flow of its blockchain is the reason why most of them are against it. They will adapt and accept things that they can have 100% control on because they can't allow decentralization. If they allow decentralized systems to operate freely, people will be able to get out of their control over time, they will start storing their money in non-custodial wallets, they will make financial transactions without any third-party involvement, and governments can't let that happen.
