And this supposedly "created" money is not backed by any thing of value, so it's akin to a number printed on a sheet of paper, unlike a chair that gets created

And this supposedly "created" money is not backed by any thing of value, so it's akin to a number printed on a sheet of paper, unlike a chair that gets created from planks of wood. You can "create" as much such money as you like, limited only by artificial rules you set yourself (with "you" being a government, because government has the monopoly on issuing money). It really doesn't matter whether it was actually printed on paper or just recorded electronically, it behaves just the same.
