Good points.
Along with DOC's thought, I've though a lot about what JW paradise would mean.
Endless fruit platters and a personal petting zoo might be nice at first, but after 347,000 years that would get old. What happens when someone plants some marijuana and starts smoking it up once the buds are ready? What if someone starts a 'business' or a competitive sports league? Are they going to get wiped off of the face of the earth? And how will those still alive cope with that kind of justice?
Its an impossibility, unless free will is removed.
