They can continue using gas stoves with cylinders.
Most of the world does that.
Of course, what actually serious chefs find is that once the subsidy for gas is removed (by removing legislation requiring utilities and buildings to provide piped natural gas), not only are induction stoves much more effective, cook faster, etc., they also keep their kitchens incredibly cool and make them much better work environments than having a bunch of gas burners around.
For the restaurants that need woks they can use a gas stove and have a gas cylinder shipped in every morning.
