Okay, so if we assume your meaning of the word "perfect" which is "same 
brain structure, same subjective experience at all times" then how do you 
propose to revive a frozen brain?

As soon as you make a copy from the frozen brain the copy will not be 
"perfect" because, according to your definition, both will have different 
subjective experience. One feels nothing, the other feels something.

So can we at least agree that it's impossible to make a frozen brain and a 
copy "perfect?"

Not true. You could make an atomically precise copy of me and my clone and I 
could be doing different things.

If both of them share the same subjective experience only means just that 
and nothing else. The argument that "same subjective experience -> same 
mind" is as valid as "I watch a movie with a friend -> we become one mind".

Wait, I didn't say anything close to that. I only said that recycling of 
atoms is a natural occurrence of Moravec transfer, that's all. It would be 
perfectly legal to perform Moravec transfer by means of nanomachines. It's 
the destructive uploading that is the problem.
