It isn't just memories that you'd have to erase. Over the course of those 10 years, imagine a man (let's call him Humphrey) stops one night to stand and stare at the star-filled heavens as a meteor-shower passes by. He enjoys the sight, but he can't stay there for ever.
During his drive home, he alters the flow of traffic for 30 complete strangers, who arrive either later or earlier depending on the actions of Humphrey. Among those 30 people, 2 catch their spouse with a lover, 3 catch part of a TV programme that they'd otherwise have missed, altering their perception about problems with their country and their world... 2 of whom change their vote at the next election because of it. And the rest of those 30 people have had their life-experience altered, even if in the tiniest amount.
Those 30 people interact with hundreds of people, who then interact with hundreds more. There is a chain-event, much like a butterfly and a tornado... demonstrating the holistic nature of humanity's experiences.
All because Humphrey stopped to admire something external to Earth's little bubble.
