They might steal it first, then figure out they don't know what to do with it later though, then just destroy it. I always lock mine when I'm out. Especially the smaller bikes are easiest to steal because they can pick it up and place it in a truck or van without even dealing with a lock too. If there were several thousand FXs around, I think you would find they would get stolen. There's a false sense of security in the low numbers in other words. My experience is that thieves steal anything not tied down. AF1 racing had a vintage e-bike stolen a couple years ago when someone broke out a window. It was light, electric, and I'm sure has never been run again both because the thief wouldn't know how to run it or fix it to run, and it would stand out like a sore thumb if you tried to sell it, get it fixed or ride it. Only thing they stole far as I know. It would have been the lightest bike in the store.....like an FX kind of.
