If scooters create problems because they're left out, fine the scooter companies for littering. That will cut into their profits, so they'll either innovate ways to make them less of a nuisance or stop doing business. Banning them makes little sense. Cities can help by increasing availability of bike racks, and scooter companies can help by providing locks on those racks to customers.
