THIS IS WHAT HAPPENS IN YOUR SCENARIO
(1)
Once we instantly pay the $19T it goes to all of our creditors.
Around 52% of them are in America.
The other 48% are foreign lenders/investors.
The $19T is out there and it shall not remain tucked away in bank accounts.
The entities who got that $19T shall start to spread it around in the form of investments everywhere in the world.
So US Dollars are now more available then they were before.
‘So what?’ you may ask.
(2)
If an importer from another country wishes to buy American products he must pay the American manufacturer in US dollars. With more US dollars readily available worldwide importer can obtain the US dollars at a lower exchange rate.
Additionally Americans will be able to get more money in bank loans because banks will want to unload the extra cash that they got (from the $19T pay-out) and put it to use rather than just have it sitting in their vault.
So now there are more US dollars floating around in people’s pockets.
What does this do?
(3)
It causes everybody who sells any product to raise the price of the product (since he knows that you and everybody else) have more money in your pocket to spend. Clothes, rent, cars, everything you can think of, goes up in price because sellers become greedy and they want your money.
(This phenomenon is called inflation.)
But everybody’s salary also went up with it, which would happen more slowly than you would like and you would suffer for a while, then there would be no problem. Well, actually there would be.
Importers from other countries would want to buy American products. If they would be willing to pay more than what the average American resident was willing to pay then manufacturers (and food producers) would cater to the foreign importers and keep prices high. And if you can’t afford it then tough sh\t. It’s a free market and manufacturers and producers don’t have to sell anything to you.
Now you would have difficulty obtaining products because prices are high because foreigners are willing to pay higher prices.
This is what typically happens during hyper-inflation which is the circumstance described above when inflation becomes too far gone because too much money was printed. The country Zimbabwe printed too much money around 20 years ago to pay off their debt and the country went into ruins due to hyper-inflation.

Another problem is that bonds become less valuable. The explanation is more technical and we’ll leave it for some other time.
