You can’t replace a body cell by cell, and you can’t know if it’d ever going to be possible. To just assume it certainly would is the same wild kind of extrapolation from past scientific progress as assuming we would be able to resist gravity or clip through walls would be in earlier times. There are natural laws that you don’t know about. That should be a hint about the issues with naive monistic materialism.
