(Answering my own question) - Installing a battery powered stove is probably less than 30 minutes of work, and the electrician selling it makes a lot of money from the sale of the expensive stove. - Running a new cable from the kitchen to the distribution board will probably take two hours or potentially even more if there is a lot of furniture in the way, but the electrician will make a lot less money because they can't sell the expensive device. So I think the answer is that battery powered stoves are just a more profitable product to sell, so that's why electricians push them instead of traditional devices.
