Why would that be?  It does not seem that those files are important. 
It is true that the listed files are lost/corrupted but if they are 
overwritten with repaired files, then new blocks would be used.

The main problem could be that it is possible that the SSD is on a 
permanent downhill trend and more issues will occur later.

The corrupted files could also be a product of RAM memory which lacks 
ECC protection and has taken a hit.  A thorough memory test is in 
order to make sure that all is ok.

It seems to me that clear is definitely worth trying but it is 
important to consider this to be an early warning of possible doom.
