I honestly don’t know why governments don’t want to OTC their BTC?

There could be a few reasons why governments are hesitant to allow over-the-counter trading of Bitcoin. One reason may be concerns about potential money laundering or illegal activities associated with OTC trading. Another reason could be the lack of regulation and control over OTC trading, which may make it difficult for governments to enforce tax laws or protect investors. Additionally, governments may also have concerns about the volatility and potential risks associated with trading cryptocurrencies. Overall, there are likely various factors contributing to governments' decisions regarding OTC trading of Bitcoin.
