(1) Since I'm proposing only a small section of Gaza at first, only a few Gazans could even be there. There are probably already at least a few Gazans who would self-select and voluntarily move into such an Israel-affiliated enclave in Gaza. (2) Everyone has a price. There probably is some promise of an incentive that would persuade Gazan parents who're slightly recalcitrant. Maybe hold out the promise of an education system that universities in the free world say they'll recruit from. Maybe just bribe the parents?
