Isn't it obvious?
That's a leftover turkey carcass from being parted out.
The groupset, wheelset, components on that is worth more than if that bike was whole.
The only reason why the crankset is still there is because the owner didn't have the crank arm puller tool, same with the pedals. Likewise most folks don't have a 32mm spanner to undo a threaded fork.
Owner knew what they were doing to get what little $ they can out of it.
OP on the other hand, not so much.
