WHOSOEVER HOLDS THIS HAMMER, IF SHE BE WORTHY, SHALL POSSESS THE POWER OF THOR.
I think this pretty much proves Busiek’s interpretation Mjolnir’s enchantment which is not just a question of who or who isn’t worthy to wield Mjolnir but who is worthy and when are they worthy enough to wield the hammer, which means an individual isn’t exactly always worthy (hence why Natasha couldn’t budge the hammer until she could and how Superman in JLA/Avengers could wield Mjolnir until he couldn’t anymore).
