Sure you can. The only reason nations avoid allowing people to become stateless is an appreciation of the burden that places on those people. But if we're pursuing a modest proposal where the government shifts its perspective to focus on "realize[ing] higher economic utility for" itself, that becomes less a concern.

At the very minimum you can "export" those low-economic-utility people by sticking them them on a barge and towing it to well into international waters where the currents will take it away (and if you're a nice government, just outside the territorial waters of some other country).
