You only have to cut the scapes once per season (and it doesn’t cause additional cloves to form, it just makes the existing ones bigger since it’s not putting energy into trying to flower). Growing hard neck garlic is easy and you get awesome garlic out of it, way better than lame ass grocery store soft neck garlic with a million cloves the size of a grain of sand (obvious hyperbole but still). Plus garlic scapes are delicious stir fried.
