Any State can unilaterally decide it will withdraw all debts it has ever contracted, and ta-da, no-one changed the definition of a debt but there is no debt anymore (which most likely wouldn’t be free of social consequences though). On the other hands, if a group of humans want to declare that there is no tree or no star in the universe, the only trick they can leverage on to shrink the count is to change the definition of these words (ta-da, good bye Pluto).
