You can't "draw energy freely". The words themselves are a contradiction. You would have work to get the energy. That work is literally a change in energy.
As for ZPE, the way any of this is being described to me doesn't make sense. That's just the lowest energy state of a quantized object. It's just the literal lowest state of energy. Energy isn't stored there, it's just the lowest amount of energy the object can have. It's not drilling oil from a well, it's claiming that you can use the fuel in your car when it's parked tonight to drive longer right now. It doesn't make any sense.
