The accounting system is what ensures that we can ACCOUNT for if such a statement is true or not.

It also allows us to characterize and understand how the capability to generate surplus has been distributed etc etc.

There is no single lump of goods and services, or a single lump of surplus. There is an economic problem of ensuring such are created in surplus and distributed to those who need them. A surplus of lawn mowing and shopping services (such as disability welfare has created in my country) could easily be accompanied by a shortage in housing. In fact one could be caused by the other.

The economy has capacity today and surplus from yesterday. Beyond that takes vigilance and accountability to maintain the system.

The fundamental question is why exactly you think a system can have some fundamental governing and observation mechanism such as debt (or equity accounting) removed and it would still maintain the same system characteristics that produce said surplus?

This is basic engineering and system architecture 101 and I would expect technologists to have more than a surface level expectation that systems do not operate magically nor label components as redundant without detailed reasoning.

The debt amount is very roughly proportional to the size of the economy.

It's also a system that is unstable in non-booming economies, drifts over time and needs periodic resets (through revolution, debt cancelling or inflation for example).

When dealing with material well-being, it makes much more sense to focus on goods and services and frame things more in the line of "would you trade a bit of wealth (smaller car or home, less Uber Eat, etc) to ensure a few unlucky people have food and roof".

Most western economies, specially one as wasteful as the US, have the luxury to make this choice. Not sharing it is a political & ideological decision, not a materially constrained one.
