That said, the jobs I’d consider non essential are things like advertising, lifestyle, gambling/gsming and the sort. They add to the economy but I’d rather not have them.
But sure, Weimar had more money than god --it just had no purchasing power.
One view is that the government has a stockpile of money and can give out money as long as it has some and has to get more to refill its stockpile lest it run out. Taxes refill the stockpile. Bonds are borrowing money to keep the pile fuller for a fixed term.
Another view is to notice that the government stockpile is connected to the money printer, so it's not really a stockpile but actually has infinite capacity and can't run out. The cons of spending too much are not running out, but rather they are the cons of overprinting money - inflation. Infinity plus anything is still infinity, so taxes don't refill the stockpile (it's infinite) but they do unprint money to prevent excessive inflation. Bonds are paying people to unprint their money for a fixed term, at the end of which it is reprinted.
These are isomorphic models of the same system, which provide different insights.
