The purpose of an Asset is to create or generate income or reduce certain expense.
The purpose of any expense is to create income.
The purpose of an income is to generate cash flow.Real cash not invoice amount.
The purpose of a debt is to produce or fund an asset which will eventually generate income.
One more thing;if you trust an asset to generate income then you can get a debt over it.If you don’t trust the asset to generate income don’t and I repeat don’t get a debt over it.
