While the situation you describe is one that some people end up using it for - it's not the real reason mosh is useful.

Where mosh really shines is when your IP is changing too frequently (a mobile problem when you are on the move) and when you are dealing with high latency connections.

When you have to ssh in somewhere over a shitty, barely working mobile data connection - mosh is a lifesaver. It makes an otherwise unusable situation comfortable and productive.

Sure, it's handy for jumping between connections, on/off wifi and so on - but that's easy to achieve many other ways with tools that have been around for a decade or two at this point.
