Yes, I do indeed believe it, in much the same way I believe in, you know, science. If the macro accounting identity is wrong, then so is double-entry bookkeeping.
The reality is that debt is a tool [good phrase
evince] and moralizing it is silly.
False. The government's debt is a net gain in financial assets for the private sector. This is a very simple principle. Whenever debt is created, so is an equal amount of credit--that is just how things work. So a government debt in the amount of $100,000 would mean net assets worth $100,000 to the private sector (we'll leave out the foreign sector for now).

Now, next, the government's debt might become "unsustainable" if it has done something silly like agreed to convert its currency on demand to another currency or to gold, but as the US is running a floating exchange rate it is "currency sovereign." Its debt can never be "unsustainable" because the government prints money whenever it spends it. Indeed, spending actually precedes taxation or borrowing if you follow the accounting in detail.
