Gold is more scarce.

In essence you are right if your definition of economical scarcity is alternative employ. If you only mean there is not that much gold, you are wrong.

Easier for certain people to control, correct, but so is everything in life. Each and everyone has their own value system. Being controlled is acquiescence to comply.

Bank to government..... Yes... But.... Banks= courts= government= post-office. Since you are describing it from the illusion, you are dealing in half truths.

There was too much silver..... Nope. There was sufficient amounts to counter balance gold. And together these PM's were a stable system.

By only focussing on gold indeed, it is not a good system. But the reason why is where you are wrong. Hence half- truth.

Step 1 was remove silver from circulation and replace it feventuslly with paper.

Step 2 remove.gold from circulation and replace it with paper.

Paper= digital.

Enter convenience and regulation.

Exactly the same type of consolidation. Again, half true.
