If you don't have a standard candle, you cannot measure distance, true.

However, there are a number of other ways to argue that highly-redshifted observations are of older things. Specifically, stars tend to be metal-poor. Galaxies are less uniform. Etc.

This argues strongly for an expansive Universe.
