Because no one has ever experienced Scrambled data on a Flash memory 
stick with a Fat Filesystem that was pulled out at a bad time......

Journaling = good, even on SSD and Flash drives.

Relying on the Mercy of Filesystem repair utilities to recover an 
inconsistent filesystem is bad.

True that performance can be improved on high reliability systems by 
disabling Journaling.  But this is pretty special case tuning, and bad 
advise to be tossing around.

Also, worrying about wear on flash drives from a bit of swapping, 
journaling, and even atime updates, (especially with relatime now the 
default.) is entirely a waste of thought.

As an example, here's the SMART status of a 128GB SSD that has been my 
system drive for over 3 years.:

I've made absolutely no attempt to minimize or reduce writes, (other 
than using spinning media for my big media files and video muxing 
projects.).  Swap is written to the SSD on regular basis, jounaling is 
left on... etc.   Over 3 years of constant use, but the drive has only 
used 4% of it's expected write cycle wear.  At this level of use, I 
should be able to go about 90 years before wear from writing to flash 
becomes an issue.
