the lawnmower will do the trick

I agree. I believe that continued cutting will keep them from ever
establishing themselves and will eventually die. In other words, no big
deal.

My wife, on the other hand, is convinced that, although the tops are being
continually cut off, the roots will continue to grow and the plant stalks
will thicken. Can someone definitively discount this theory?

Plants cannot grow without leaves. Cut their leaves off and they are unable
to perform photosynthesis and thus unable to eat and grow.
