There is money and there is real resources. Money is just a real resources distribution technology.
What is important is the real resources of a society. We (as a country, whatever is your country, if it has its own money) will never be short of money.
It can, however, get short of real resource if it leave infrastructure and knowledge diminish.
The available capital far outstrips realizable capital. In other words money isn't a direct product of productivity but rather of trust in the ability to be able to realize the capital. There aren't enough things to buy from the available capital we are literally betting on not everyone realizing their capital at once if that was the case we would be failing completely.
So borrowing from the future is the best way to think about it we are betting on the ability to keep the system of realized capital much much lower than available. Money is not a thing it's a concept of trust.
All that would happen is prices would go up dramatically basically repeating germany in the 30's if not worse.
