Invoking the shoreline paradox is very interesting, but not quite fitting. To continue the analogy, your task isn't to measure the shoreline length (which cannot be meaningfully done), it's to physically walk it. Walking the shoreline _can_ be done, and someone who's walked it many times in a practical way before would be able to give a reasonable estimate.
