I don’t forsee a 14 mm chain being cut by bolt cutters that would be reasonable to carry around. Especially considering the hardness of the steel it’s made of. I just don’t think it’s worth the effort given the amount of people using cable and D locks that can be cut with handheld shears.
The average Joe won’t bother stealing your bike, but the pros will simply take a bolt cutter and remove your chain or lock.
A good bolt cutter is a small investment for people who do this for a living.
