If you set up sync, the yanking won't cause damage but the perpetual
syncing will; your choice.

How about, train yourself to use a computer properly or design a flash
memory that does not have a write-limited life expectancy. Your
attitude is as if you were complaining that your device with a NiCad
battery dies if you leave it in the charger all the time; memory effect.
Lithium-Ion solved that for some applications but then again, LI doesn't
like to be charged only once a month but likes to live in a charger.
Right now, for flash memory devices there is no choice. Linux is
protecting you from damaging both the file system (caused by just
yanking) and the underlying device (caused by frequent syncing). You
are free to circumvent both and welcome with open arms (and wallet) all
the instability for which 'doze if infamous.
Doug.
