That is the very basis of our currency, and the basic idea is a good one in an idea-heavy economy more reliant on innovation than natural resource constraints. Also, if truly becomes too much we will just have one of the many many currency changes. My grandparents lived with about five (could be as many as seven) currencies throughout their (German) lives, for example.
As long as the real values remain, the factories, the people, the roads, the buildings, that is not a problem overall. It's not like people can emigrate to alien worlds, and on earth the places with the best real economy will be where they will go - have to go.
Money is the carrot dangled in front of us to keep us moving and to create real value things. The carrot can be updated and changed if the current one starts to lose its appeal, it is not what ultimately matters. The point of view of an individual and the big picture are very different things.
And I'll just use this opportunity to recommend David Graeber's "Debt: The First 5,000 Years" - a wonderful book about the history of economy, demonstrating how it always boils down to effective use of debt.
There are tons of great parts in it, but one that really stuck with me is his analysis of the social dynamics whereby when someone brings you a gift or otherwise does something expensive for you, you are temporarily in debt to them, and the polite expectation is that you always pay it back in a way whereby you give more than you owe, such that they will then be in debt to you (generally for approximately the same amount), and the relationship can continue oscillating, with each of you being in debt about half the time. Paying back exactly what you were given and not a penny more is thus considered to be an indication that you want to discontinue the relationship.
