Gold standard serving as a fiscal straitjacket is precisely why it has be removed by governments time and time again. Removing a gold standard benefits the government and those in power and is a detriment to the people and the value of their labor. Not having a gold standard removes the physical requirement for government to behave with fiscal responsibility.

The number of times that gold standards have been ended isn't proof that gold standards don't work. It is proof that people in power will remove obstacles in the way of achieving their agenda.

People in power are still people. People cannot be trusted to be responsible with massive amounts of money when there is no personal penalty for being fiscally irresponsible.
