, but the US dollar is recognized as having value because it is legal tender for all goods and services public or private. <-- WTF
HAHAAH I didn't even see this. You really are clueless.
Yes, debt from goods/services public or private.
I give good or service to you, I have a debt (lets say, -1) from delivering this good or service.
Legal tender is suitable to repay this debt.
You give me (+1) legal tender to fill the debt.
The giving of a good or service constitutes a debt. Legal tender repays that debt.
And the problem is???
