The original comment just says "because of entropy". It's not an explanation, it's an appeal to a black-box technical term. So I pointed out an obvious way in which that term did not apply, since we're rather further than 100 years from the heat death of the universe.
Yes, human bodies by default incur damage and stop functioning within ~100 years. But what prevents that damage from being repaired, other than our ignorance? Are you/they actually claiming it literally violates the laws of physics to repair a human body? Because if not, I reject the appeal to entropy. Entropy is a very specific thing; it is not a generic stand-in for "stuff must break down".
