Your examples illustrate someone lying. Merely arriving at the summit of Everest by assisted means does not make one a liar. People do many things - summiting among them - for their own amusement, not to make grandiose claims. Jon Krakauer "bought" (or had it purchased on his behalf) his way to the top of Everest and to my knowledge has not equated himself with Sir Edmund Hillary to date.

If teleportation was invented, would it cheapen the pioneer's accomplishments if we could just buy a ticket to teleport to the top, grab a peek, and teleport home?
