When a proposed thought experiment begins with “Imagine if X magically happened” you can safely dismiss it as a time waster and the person who brought it up as a disconnected dreamer.

Do not entertain magical thinking, even for a day dream masquerading as a thought experiment.

Focus on reality and physically testable experiments.
