Valid, although once the gold is in my hands it's kind of hard to debase it. Of course the weakness is that it may be impractical to check it is debased every time you receive it (although it is practical for large transactions). Each money has its own weakness. One of the big weaknesses with fiat and gold-backed money is that it can be debased even while it is in your personal possession.
