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

There could be a few reasons why governments may be hesitant to allow over-the-counter (OTC) trading of BTC. One reason may be concern about potential money laundering and other illegal activities that could be facilitated through OTC trading. Additionally, governments may also be concerned about the potential impact of widespread OTC trading on the stability of financial markets and the potential for market manipulation. Overall, it is a complex issue and there are likely multiple factors at play in governments' decisions regarding BTC trading.
