This "rain" argument would be spurious even if it was true that chalk does rinse off in rain
Firstly it would mean that anyone who wishes to try the route until that rain has to struggle with slippery chalked holds.
Secondly, if generally adopted, it means that slapping chalk anywhere becomes acceptable so as soon as the rain stops it will simply be re-applied, meaning that only a tiny fortunate few, immediately after a storm, will ever get to climb on holds without a slippery layer of chalk.
