The dollar is no longer backed by gold.
The final connection to gold was ended by Nixon when France thought America was spending too much money on the Vietnam War. Up to that time, nations still could exchange dollars for gold, and France decided to do just that.
Since then, we have been in the petrodollar world. The dollar was tied to oil instead.

That only works if your money is based on the value of gold. That stopping being a concern in the 1970s.
No reason to take away gold today.
