...and yeah how aggressive anyone, any institution or any government could be may well tie into their own particular circumstances, and not everyone (including a country like El Salvador) can afford to be even close to as aggressive as Michael Saylor (and MSTR), and I would not even say that Saylor is going overboard for his (and his company's) own particular circumstances, but he is capable of being way more aggressive (and over-leveraged) than many individuals and/or governments could afford to be..
Everything you have said JayJuanGee is correct but it will be easier for an individual to pursue the bitcoin course than nations. An individual can easily bypass restrictions placed on bitcoin by the government and other institutions. I can decide to live a fiatless life and convert all my money to bitcoin and use a trusted friend or relative to engage in fiat transactions. I'll continually remain private while my relatives assist me in converting my Bitcoin each time I want to use fiat.
But nations have international trade partnerships, debt servicing obligations, and other financial responsibilities. They will always be forced to use fiat to make payments because most of these trade partners and lending organizations will never accept bitcoin as payment. This means countries like El Salvador still have to tread with caution because no country can survive alone. The country needs to still play the fiat game until Bitcoin becomes a major and acceptable currency in the international market.
