The problem arises when the programmer *deliberately* does unaligned
loads and stores in order to improve performance. Or rather, if the
programmer knows that the hardware supports unaligned loads and stores,
he/she can use that to write faster code in some special cases.

Or the compiler or standard library author can do the same.
