The only thing 'obvious' is that you are confusing force with energy.

Wrong assumption. Charges have no energy. How much 'energy' does a
magnet have to remain stuck on my fridge door? How much 'energy' do you
have to keep you from falling to the Moon? How much 'energy' does a pen
have as it lays on my desk? The force is there, but no energy, it is
balanced.
