This is exactly what all the governments want. They want to control all transactions. they want to be able to prosecute buyers and sellers to stop some illegal actions can be easy made using bitcoin. As Bitcoin is decentralized, They can't change Bitcoin, They only try to stop people using it. In any situation a day all of them will accept bitcoin as a global currency.
With the bitcoin price getting more and more higher, those who own bitcoin are found earning more money than before and this puts them in a questionable situation where goverments sees them as citizents who are earning money without any taxes, a couple of years ago content creators on youtube and streamers were in the same situation where they were earning money from donations subscribtion and sponsors without having to pay taxes, until recently where some goverments started regulating this kind of industry, and they started paying taxes for their equipments and others things related to their work, and it will be a matter of time bfore we see the same thing happening whith the crypto currency and the bitcoin in pirtuciliar, where taxes will be on mining machines, or increasing the electricity bill for those who mine bitcoin.
