1) You seem to be saying that you want the USG (or all governments) to start a mining operation in order to replace tax receipts.
2) You seem to think that profits from mining are/will be enough to replace current/future government expenditures.
How familiar are you with reviewing corporate P&L’s? Not even the most profitable miners are capable of replacing taxes.
Lastly, “if governments were the ones to establish and maintain our monetary infrastructure” is not a pro-bitcoin argument with which I’m familiar.
