Don't forget what the explanation is based on: the use of several sockets simultaneously. Examples. I don't find the logic or causality in your answers.
But you really have to want to overlook it.
Very many sockets because of many devices. Some of these devices
in my eyes unnecessary. Causality: Many devices require many sockets. Logical consequence: Fewer devices require fewer sockets. Replacing a kettle with an induction-capable pot frees up one socket. But yes, ecologically it would be better to keep using the kettle if it's already there.
Kettle, coffee machine, phone and another kitchen appliance, leaving two for interchangeable devices such as toaster or food processor. The same applies to the counter: hand blender, deep fryer, rice cooker
See, that's what I mean. For me, kettle, coffee machine, deep fryer, and toaster are unnecessary, ergo space wasters, ergo unnecessary sockets are kept available for them. Think about what that costs in terms of space and thus money... and I still regularly toast, fry, and make coffee.
Filling the countertop and cabinets with all these things just makes zero sense to me. But hey, everyone is different, and that's how it should be.
I just can't get past the logic of "wondering" about a specific device but having five others to make up for it (each demanding its own socket). Where's the fucking sense in that?
