Wouldn't there be an argument for a kettle, where as you heat it some heat (including steam) is lost through the top?

Yes, but evaporative cooling happens in a microwave too.

The microwave has an enclosed cavity that captures this loss and so reduces future loss as the water heats.

Microwaves don't have an airtight seal. If they did you would be able to blow the door off if you heated a large enough bowl of water.

Also, the kettle heats a certain quantity water of which only some is used. A mug in the microwave would heat only the water you use.

You don't have to fill kettles up to the top to use them
