European here that doesn't drink tea yet still has a kettle.

> they won't say "because I only have 120V outlets in the kitchen." They'll say it is because they don't need a kettle.

Well no they wouldn't say that, unless they have experience of 240v perhaps.

They might reasonably say that it's too slow. Or maybe they're aware that kettles are 'just slow' and so arrange their lives so that they don't need a kettle, in which case they would say "I don't need a kettle".
