yes if the bitcoin system will be centralized and will be controlled by the government then probably it will happen since 2025 is still far to happen. There are many set of events to happen within these years and we could not expect also with the bitcoin system. US had already embracing the bitcoin system and i guess they will relatively conduct a study and then modify some bitcoin's feature that could lead to its destabilization and price of btc will be controlled over by the government. So as of now we have to enjoy the bitcoin has to offer us.
You are talking about probable events. But this, unfortunately, kills the idea of the crypto currency.
If the sellers themselves'll begin to offer to pay by crypto, it will spread. But this is not to be liked by the trade-controlling organizations.
