They can talk all they want, but just try actually doing it. Does that mean 7 years of not being hounded into doing whatever Israel mission is on the roster? Does that mean 7 years of not being expected to waste all your money pious-sneering (plus another one because you need a whole year after reinstatement to pious-sneer)? Does that mean 7 years of not getting up early Saturday morning for field circus? Or not having to do those duties, such as ragazine duty? Being hounded to become an assistant hounder?
Besides, 7 years is plenty of time to do research on the whole religion. If they find out that the religion is not even true according to its own damnation book, or that the whole damnation book is black magic against the whole human race, they might not want to go back to the cancer at all. Then they get zero money for the Worldwide Damnation Fund. Zero Israel missions (instead, they just buy the monster box of silver or take their own vacation to wherever they see fit). Zero field circus, zero suit dry cleaning bills, zero poisonburgers, zero gas wasted, zero impact on throwing away rubbish from their poisonburgers or suit dry cleanings into the landfill (do those buildings even have recycling bins?).
And, any children will actually get to have their ice cream cones.
