Total BS. Apple only needs country-level address for tax compliance as local jurisdictions (states, cities, etc.) aren't allowed to impose their own taxes on digital sales anywhere.
Even assuming that's true, the laws could change and the moment they do, Apple would need to comply with the tax laws. If Apple doesn't collect anything more than country-level location, and states start imposing taxes on digital sales, then Apple would have no way to comply with the law.
