Since the governments have not been totally up to speed with what bitcoin and is and how it works, they are mostly staying in the ignorance is bliss and just tax it heavily to discourage people from investing in bitcoin or trading in it.
They are not willing to build a condition in which the people are able to use it freely and trade it while the government gets some nominal taxation from every transaction.
They are centralized and will be always centralized whereas Bitcoin blockchain is decentralized, so it's unrealistic to hope that governments will prefer to provide good conditions for Bitcoin to grow up more. They consider Bitcoin as threats to their centralized and censored financial systems, so that they know what they need to do for decelerating Bitcoin adoption growth.
They only have been forced to change their systems and legalize Bitcoin when it was strong enough and citizens will vote the leading party out if their governments want to kill Bitcoin. Fortunately, around the world the majority of nations have democracy than dictatorship so the general global political status gives Bitcoin great opportunities to grow more.
For now we should accumulate coins as much as we can. We dont know how in future governments will react and move, for the US it has been good and if the other countries follow suit then the biggest holders will be the richest.
Stacking more satoshis, more bitcoins, holding them in secure non custodial wallets are what we have to do to secure our wealth against inflationary issues of fiat currency.
The purchasing power of satoshis/ bitcoins has increased strongly over time, and it's big mistake if we waste very great opportunity Satoshi Nakamoto gave us.
