ELI5: Money stopped representing gold in the 1970's (I think).. So What does it represent now? Does this mean the goverment can just make infinite ammount of cash?

Money is just digits nowadays, it doesn't represent the total gold the state has. So can banks and goverment just change the digits?

Governments could theoretically change the digits but it wouldn’t actually change the value of things. If the US government decided to add two digits to the dollar so $1 is $100, the price of everything would just rise by an equal amount. 

Ultimately, what gives money value is everyone agreeing it has value. A dollar is worth a dollar because we all accept dollars as payment. But a more tangible reason is that everyone needs it to pay taxes every year. It doesn’t really matter if the government takes dollars, gold, or seashells. If you have to come up with $10,000 in seashells or go to prison, seashells have value.
