This is mostly a matter of convenience, not a deeply considered choice. 
Since cell membranes are well preserved by standard histological 
methods, why even investigate frozen tissue as an option?


I like fixation for its ability to function regardless of a support 
infrastructure. However, I suspect I would still prefer to have my brain 
stored in a dedicated institution trying to protect it than to trust the 
overall environment out there.

Max's point about revival options is important: we do not just want to 
minimize damage during preservation, we also want to make the resulting 
product amenable to as many possible future revival technologies as 
possible.
